Description

Technical Field

[0001] The present application relates to the technical field of power supply circuits, and in particular to a multi-phase power supply circuit and an integrated chip circuit. Background Art

[0002] The production of integrated circuits requires compatibility with multiple chips, that is, the same PCB (Printed Circuit Board) can meet the use requirements of one chip and the use requirements of another chip at the same time.

[0003] In some integration methods, corresponding power supply circuits are designed on the PCB board for the chips that need to be compatible. However, the voltage value requirements and current of different chips may be different. For example, a chip requires a voltage of 0.8 volts and a voltage of 0.9 volts. To provide power to this chip alone, two circuits with different voltages need to be set up. If compatibility with other chips is required, other power supply circuits need to be set up separately on the basis of these two circuits to provide power for other chips. This integration method requires a larger space layout, especially for multi-phase power supply circuits, which require multiple driving voltage converters to provide voltage and current. The space layout required is larger, resulting in the space of some PCBs being unable to meet the layout requirements of multiple chips, resulting in compatibility failure. Summary of the invention

[0035] Figure 6 This is a structural diagram of a multi-phase power supply circuit according to an exemplary embodiment of the present application.

[0036] The above drawings have shown clear embodiments of the present application, which will be described in more detail later. These drawings and text descriptions are not intended to limit the scope of the present application in any way, but to illustrate the concept of the present application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION

[0037] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0038] The multi-chip compatibility requirement is to meet the needs of multiple chips on one PCB. For example, if chip A and chip B are required to be compatible, on one PCB, the layout of the PCB board is such that chip A can be set on the PCB board to meet the needs of chip A. If chip A is replaced with chip B, the layout of the PCB board can also meet the needs of chip B.

[0039] The voltage requirements and single-ball current requirements of the chip may correspond to different power circuit designs. Therefore, how to set up a multi-phase power circuit on a PCB board to meet the compatibility requirements of multiple chips becomes a problem that needs to be solved.

[0040] In some embodiments, corresponding power supply circuits may be designed on the PCB board for the chips that need to be compatible, taking the case where chip A and chip B need to be compatible as an example.

[0041] Chip A requires a voltage of 0V8_VDD (0.8 volts digital voltage), and the required current at 0.8 volts is 82A (amperes). It requires a voltage of 0V8_VDDA (0.8 volts analog voltage), and the current at 0.8 volts is 20A. The same voltages can be combined, that is, chip A has a power supply requirement of 102A at 0.8 volts.

[0042] Chip B requires a voltage of 0V8_VDD, with a current of 70A at 0.8V, and a voltage of 0V9_VDDA (0.9V analog voltage), with a current of 60A at 0.9V. That is, chip B has power requirements of 70A at 0.8V and 60A at 0.8V.

[0043] In a multi-phase power supply setting, the controller is usually paired with a drive MOS. A controller can support two loop voltage outputs, and each loop can support at least four power phases (phases, i.e. drive MOS). Each phase has a maximum supported current output.

[0044] If the maximum supported current output of each phase is 35A, then Figure 1 As shown, setting a multi-phase power supply for chip A alone requires a controller and three drive voltage converters sharing one loop. Figure 1 It is shown in the figure that loop A of the controller supplies power to chip A, loop B is not on, i.e. float, the controller and the driving voltage converter provide chip B with a voltage of 0.8 volts, and the three driving voltage converters can provide the current required at a voltage of 0.8 volts, i.e. the three driving voltage converters can provide the current 102A required by chip A at a voltage of 0.8 volts.

[0045] If the maximum supported current output of each phase is 35A, then Figure 1 As shown, setting a multi-phase power supply for chip B alone requires a controller and four drive voltage converters. The two loops of the controller are connected to two drive voltage converters respectively. Figure 2 It is shown that the controller's loop A and the two connected drive voltage converters provide a voltage of 0.8 volts, and the two drive voltage converters can meet the chip's current requirement of 70A at a voltage of 0.8 volts. The controller's loop B and the two connected drive voltage converters provide a voltage of 0.9 volts, and the two drive voltage converters can meet the chip's current requirement of 60A at a voltage of 0.8 volts.

[0046] Chip A and chip B are compatible on the same PCB board. Figure 3 As shown, a controller and 5 driving voltage converters are required. Loop A is connected to 3 driving voltages to provide a voltage of 0.8 volts, and the 3 driving voltages meet the current demand of chip A at 0.8 volts and the current demand of chip B at 0.8 volts. Loop A is connected to 2 driving voltages to provide a voltage of 0.9 volts, and the 2 driving voltages meet the current demand of chip A at 0.9 volts. In this way, Figure 3 The structure in can achieve compatibility between chip A and chip B, that is, Figure 3 The structure in can power both chip A and chip B.

[0047] Figure 3 The structure in the figure requires space for two more driving voltage converters than the original separate design of chip A, and space for one more driving voltage converter than the original separate design of chip B. Moreover, some PCB applications may be compatible with more than two chips, which will lead to an increase in the number of driving voltage converters by multiples of the chips.

[0048] In some devices, the space of the PCB is limited and may not be able to accommodate the addition of a large number of driving voltage converters, resulting in a layout failure. The addition of driving voltage converters also leads to an increase in cost.

[0049] In some embodiments, a multi-phase power supply circuit is proposed. For compatible chips, one chip can reuse the driving voltage converter of another chip, thereby reducing the number of driving voltage converters in the multi-phase power supply circuit and reducing costs. The multi-phase voltage circuit can also achieve compatibility with multiple chips.

[0050] The technical solution of the present application and how the technical solution of the present application solves the above-mentioned technical problems are described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0051] refer to Figure 4 , provides a multi-phase power supply circuit, including a controller, a first number of first drive voltage converters and a second number of second drive voltage converters.

[0052] The controller includes a first output module that outputs a first signal and a second output module that outputs a second signal; the first number is the number of driving voltage converters required by the first chip at a first voltage corresponding to the first signal; the second number is the number of driving voltage converters required by the first chip at a second voltage corresponding to the second signal.

[0053] The first output module is connected to the first driving voltage converter through a switching device and is connected to at least a third number of second driving voltage converters through a switching device, and the second output module is connected to the second driving voltage converters through a switching device, and the third number is the difference between the number of driving voltage converters required by the second chip at the first voltage and the number of driving voltage converters required by the first chip at the first voltage.

[0054] In one embodiment, the first output module outputs a first signal, and the first signal can be converted into a first voltage through a driving voltage converter. The first signal can be converted into the first voltage through the first driving voltage converter or the second driving voltage converter, and different first voltage values ​​can be obtained by controlling the value of the first signal.

[0055] The first output module and the second output module correspond to two loops in the controller. The first signal and the second signal may be PWM (Pulse Width Modulation) signals, which are not limited here.

[0056] In one embodiment, the second output module outputs a second signal, and the second signal can be converted into a second voltage through a driving voltage converter. The second signal can be converted into the second voltage through the first driving voltage converter or the second driving voltage converter. By controlling the value of the second signal, different values ​​of the second voltage can be obtained.

[0057] In some embodiments, the first chip and the second chip need to be compatible on a PCB board, and a multi-phase power supply circuit needs to be set for the first chip and the second chip, and the multi-phase power supply circuit can be compatible to supply power to the first chip and the second chip.

[0058] In some embodiments, the first chip may require a voltage of one value, such as the second voltage. In other embodiments, the first chip may require voltages of two values, such as the first voltage and the second voltage.

[0059] In some embodiments, the second chip may require a voltage of one value, such as a first voltage. In other embodiments, the second chip may require voltages of two values, such as a first voltage and a second voltage.

[0060] In some embodiments, the first chip is used as a reference chip, and the number of driving voltage converters required by the first chip is set to the number of driving voltage converters in the multi-phase power supply circuit, that is, the number of driving voltage converters required by the first chip is the sum of the first number and the second number.

[0061] In some embodiments, for the first chip, the number of driving voltage converters required at the first voltage is the first number. Since the first driving voltage converter is connected to the first output module to provide the first voltage, the first number can be calculated by dividing the current value required by the first chip at the first voltage by the current value supported by a single first driving voltage converter. The obtained value is rounded up to the first value.

[0062] If the current value required by the first chip under the first voltage is 100, and the current value supported by the single first driving voltage converter is 35, then the first value is 3.

[0063] Similarly, for the first chip, the number of driving voltage converters required at the second voltage is the second number. Since the second driving voltage converter is connected to the second output module to provide the second voltage, the second number can be calculated by dividing the current value required by the first chip at the second voltage by the current value supported by a single second driving voltage converter. The obtained value is rounded up to be the second value.

[0064] In some embodiments, when the switching device between the first output module and the first driving voltage converter is connected, the first output module and the first number of first driving voltage converters can meet the first voltage of the first chip and the current value required under the first voltage; when the switching device between the second output module and the second driving voltage converter is connected, the second output module and the second driving voltage converter can meet the second voltage of the first chip and the current value required under the second voltage.

[0065] The number of driving voltage converters required by the second chip at the first voltage is greater than the number of driving voltage converters required by the first chip at the first voltage. Therefore, the difference between the number of driving voltage converters required by the second chip at the first voltage and the number of driving voltage converters required by the first chip at the first voltage is taken as the third number.

[0066] The method for calculating the number of driving voltage converters required by the second chip at the first voltage may refer to the method for calculating the number of driving voltage converters required by the first chip at the first voltage.

[0067] In some embodiments, the first output module is connected to at least the third number of second driving voltage converters through a switching device. When the switching device between the first output module and at least the third number of second driving voltage converters is connected, the switching device between the first output module and the first number of driving voltage converters is connected, and the switching device between the second output module and at least the third number of second driving voltage converters is disconnected, the first output module and at least the third number of second driving voltage converters and the first number of driving voltage converters can meet the first voltage of the second chip and the current value required under the first voltage. In some embodiments, the first number can be zero, and the second number is not zero.

[0068] In an embodiment of the present application, a multi-phase power supply circuit is provided. When the multi-phase power supply circuit needs to be compatible with a first chip and a second chip, a switching device is set between a controller and a driving voltage converter, and according to the difference in driving voltage converters required for the first chip and the second chip at different voltages, the second driving voltage converter originally required for the first chip at the first voltage is reused. When powering the first chip and the second chip respectively, power can be supplied to the first chip or the second chip by setting the connection and disconnection of the switching device.

[0069] In some embodiments, the sum of the first number and the second number is greater than or equal to the sum of the number of driving voltage converters required by the second chip at the first voltage and the number of driving voltage converters required by the second chip at the second voltage.

[0070] In this embodiment, if the number of driving voltage converters required by the first chip is greater than the number of driving voltage converters required by the second chip, the first chip is used as the reference chip, and the number of driving voltage converters required by the first chip is taken as the sum of the first number and the second number.

[0071] The number of driving voltage converters required by the first chip includes the number of driving voltage converters required by the first chip at the first voltage and the number of driving voltage converters required by the first chip at the second voltage, and the number of driving voltage converters required by the second chip includes the number of driving voltage converters required by the second chip at the first voltage and the number of driving voltage converters required by the second chip at the second voltage.

[0072] In the embodiment of the present application, the chip with the largest number of required driving voltage converters among the compatible chips is used as the reference chip, and the number of driving voltage converters of the reference chip can be a multi-phase power supply circuit.

[0073] In some embodiments, the number of driving voltage converters required by the first chip includes the number of driving voltage converters required by the first chip at the first voltage and the number of driving voltage converters required by the first chip at the second voltage, and the number of driving voltage converters required by the second chip at the first voltage is greater than the number of driving voltage converters required by the first chip at the first voltage. In this case, the number of driving voltage converters required by the second chip at the second voltage must be less than the number of driving voltage converters required by the first chip at the second voltage, and less than the value obtained by subtracting the third number from the second number. Thus, after subtracting the third number of second driving voltage converters from the second number of second driving voltage converters, the remaining second driving voltage converters can still provide the second chip with the second voltage and the current value required by the second chip at the second voltage.

[0074] In some embodiments, the current value provided by the first number of first driving voltage converters is greater than or equal to the current value required by the first chip under the first voltage.

[0075] The current value provided by the second number of second driving voltage converters is greater than or equal to the current value required by the first chip under the second voltage.

[0076] In this way, when the switch devices between the first output module and the first number of first driving voltage converters are turned on, the first voltage and the current at the first voltage required by the first chip can be provided to the first chip.

[0077] When the switch devices between the second output module and the second number of second driving voltage converters are turned on, the second voltage and the current at the second voltage required by the first chip can be provided to the first chip.

[0078] The current value provided by the first number of first driving voltage converters and the third number of second driving voltage converters at the first voltage is greater than or equal to the current value required by the second chip at the first voltage. In some embodiments, the switch device is a zero-ohm resistor.

[0079] The first output module / second output module and the driving voltage converter can be connected or disconnected by setting the switch device to be on or off. When the switch device between the first output module / second output module and the driving voltage converter is on, the first output module / second output module and the driving voltage converter are connected; when the switch device between the first output module / second output module and the driving voltage converter is on, the first output module / second output module and the driving voltage converter are disconnected.

[0080] In other embodiments, the switching device may also be other devices that can be set to conduct or disconnect between the first output module / second output module and the driving voltage converter, such as a reserved precision resistor or a short pad (tin block), etc., which is not specifically limited here.

[0081] In some embodiments, Figure 5 As shown, the first output module includes a plurality of first output interfaces, each of which is connected to each first driving voltage converter respectively, and each of which is connected to each second driving voltage converter of the third number of second driving voltage converters respectively.

[0082] The second output module includes a plurality of second output interfaces, and each second output interface is respectively connected to each second driving voltage converter.

[0083] In some embodiments, the first output interfaces of the first output module can output a first signal, one first output interface is connected to a first driving voltage converter through a switching device, and one first output interface is connected to a second driving voltage converter among a third number of second driving voltage converters through a switching device.

[0084] Figure 5 In the figure, M identifies the first output interface and N identifies the second output interface.

[0085] In some embodiments, the first output interface may also be connected to each second driving voltage converter via a switching device.

[0086] A second output interface is connected to a second driving voltage converter through a switch device.

[0087] In some embodiments, an integrated chip circuit is provided, comprising: Figure 4 A multi-phase power supply circuit and a first chip.

[0088] The first driving voltage converter is connected to the first chip, and the second driving voltage converter is connected to the first chip.

[0089] The switch device between the first output module and the first driving voltage converter is turned on, and the switch device between the second output module and the second driving voltage converter is turned on.

[0090] The switching devices between the first output module and the third number of second driving voltage converters are disconnected.

[0091] When the multi-phase power supply circuit provides power to the first chip, the switching device between the first output module and the first driving voltage converter is turned on to provide the first chip with a first voltage and a current at the first voltage, and the switching device between the second output module and the second driving voltage converter is turned on to provide the first chip with a second voltage and a current at the second voltage.

[0092] Figure 4 In the figure, X identifies a switching device.

[0093] In some embodiments, the switching device between the first output module and the third number of second drive voltage converters is disconnected to prevent the first output module and the second output module from simultaneously outputting the first signal and the second signal to the third number of second drive voltage converters, causing the third number of second drive voltage converters to short-circuit.

[0094] In some embodiments, the first driving voltage converter is connected to the first chip via a first output line, and the first output line can withstand a current value greater than a current value required by the first chip at the first voltage.

[0095] The second driving voltage converter is connected to the second chip through a second output line. The second output line can withstand a current value greater than a current value required by the first chip under the second voltage.

[0096] In some embodiments, when powering the first chip, the first driving voltage converters all output the first voltage, so that each first driving voltage converter can be connected to the first chip through a line, namely the first output line. At the same time, in order to ensure the safety of the line, the current value that the first output line can withstand is greater than the current value required by the first chip under the first voltage.

[0097] In some embodiments, the second driving voltage converters all output a second voltage. Therefore, since the first voltage and the second voltage are different, each second driving voltage converter can be connected to the first chip through a line that is different from the first output line. That is, in order to ensure the safety of the second output line, the second output line can withstand a current value greater than the current value required by the first chip at the first voltage.

[0098] In some embodiments, an integrated chip circuit is provided, comprising: Figure 4 The multi-phase power supply circuit and the second chip.

[0099] The first driving voltage converter is connected to the second chip, and a third number of second driving voltage converters connected to the first output module are connected to the second chip.

[0100] The switch device between the first output module and the first driving voltage converter is turned on, and the switch device between the first output module and the third number of second driving voltage converters is turned on.

[0101] The switching devices provided in the routes connecting the second output module and the third number of second driving voltage converters are disconnected.

[0102] In some embodiments, the multi-phase power supply circuit supplies power to the second chip, the switching device between the first output module and the first number of first drive voltage converters is turned on, and the switching device between the first output module and the third number of second drive voltage converters is turned on, thereby forming a loop to provide the second chip with the first voltage requirement and the current value requirement at the first voltage.

[0103] In some embodiments, a third number of second driving voltage converters and the first driving voltage converter connected to the first output module are connected to the second chip via a third output line, and the third output line can withstand a current value greater than the current value required by the second chip at the first voltage.

[0104] In some embodiments, a third number of second drive voltage converters and the first drive voltage converter connected to the first output module both output the first voltage, so that the third number of second drive voltage converters and the first drive voltage converter connected to the first output module can be connected to the second chip via a line, namely the third output line. At the same time, in order to ensure line safety, the current value that the third output line can withstand is greater than the current value required by the second chip at the first voltage.

[0105] In some embodiments, the second chip may or may not require the second voltage.

[0106] If the second chip requires a second voltage, in some embodiments, at least a fourth number of second driving voltage converters are connected to the second chip, the fourth number being the number of driving voltage converters required by the second chip at the second voltage.

[0107] At least a fourth number of switching devices between the second driving voltage converters and the second output module are turned on.

[0108] The switching devices between the second output module and the third number of second driving voltage converters are disconnected.

[0109] The fourth number of second driving voltage converters is different from the third number of second driving voltage converters.

[0110] The calculation method of the fourth number may refer to the calculation method of the second number, and the fourth number is less than the second number minus the third number.

[0111] In some embodiments, the switching devices arranged in the route connecting at least a fourth number of second driving voltage converters and the second output module are turned on, so that the at least a fourth number of second driving voltage converters and the second output module can provide the second voltage required by the second chip and the current value at the second voltage.

[0112] The switching device in the route connecting the second output module and the third number of second driving voltage converters is set to be disconnected to avoid the first output module and the second output module simultaneously outputting the first signal and the second signal to the third number of second driving voltage converters, resulting in a short circuit of the third number of second driving voltage converters.

[0113] At least the fourth number of second drive voltage converters is different from the third number of second drive voltage converters, which can be regarded as at least the fourth number of second drive voltage converters whose switching devices are turned on between the second output module is different from the third number of second drive voltage converters whose switching devices are turned on between the first output module.

[0114] The number of the at least fourth number of second driving voltage converters is greater than or equal to the fourth number and less than or equal to the second number minus the fourth number.

[0115] In some embodiments, when a number greater than the fourth number of second driving voltage converters is connected to the second chip, the number of driving voltage converters that exceeds the number of driving voltage converters required by the second chip at the second voltage provides the second chip with the current value required at the second voltage. Thus, for the second driving voltage converters greater than the fourth number connected to the second chip, the current passing therethrough becomes smaller. For example, the maximum current supported by the second driving voltage converter is 35A, the current value required at the second voltage is 102A, and the fourth number is 3. Three second driving voltage converters are used to provide the second chip with the current value required at the second voltage, and each second driving voltage converter supplies a current of 33A. Four second driving voltage converters are used to provide the second chip with the current value required at the second voltage, and each second driving voltage converter supplies a current of 22A. The current value supplied by each second driving voltage converter becomes smaller, which can extend the service life of the second driving voltage converters greater than the fourth number.

[0116] In some embodiments, the controller can control and adjust the output of the first signal and the second signal of the first output module and the second output module through the internally configured firmware. When the multi-phase power supply circuit is compatible with different chips, there is no need to change the layout of the multi-phase power supply circuit. It is only necessary to burn the corresponding firmware in the controller for control when the multi-phase power supply circuit is compatible with different chips.

[0117] In this embodiment, Figure 1 and Figure 2 Taking chip A and chip B as examples, chip B requires 4 driving voltage converters and chip A requires 3 driving voltage converters. If chip B is regarded as the first chip, the multi-phase power supply circuit compatible with chip B and chip A includes 4 driving voltage converters.

[0118] 0.8 volts corresponds to the first voltage, and 0.9 volts corresponds to the second voltage. It is determined that phase1 and phase2 of the four driving voltage converters are the first driving voltage converters, and phase3 and phase4 are the second driving voltage converters. The first number and the second number are 2, and the corresponding calculated third number is 1.

[0119] like Figure 6 As shown, the first output module in the controller includes four first output interfaces, namely PWM1, PWM2, PWM3 and PWM4, and the second output module includes two second output interfaces, namely PWM5 and PWM6.

[0120] Among them, PWM1 and phase1 are connected through a switching device, PWM2 and phase2 are connected through a switching device, PWM5 and phase3 are connected through a switching device, and PWM6 and phase4 are connected through a switching device.

[0121] PWM3 and phase3 are connected via a switch device, and PWM4 and phase4 are connected via a switch device.

[0122] When the switching device between PWM1 and phase1 is turned on, the switching device between PWM2 and phase2 is turned on, the switching device between PWM5 and phase3 is turned on, the switching device between PWM3 and phase3 is turned off, the switching device between PWM4 and phase4 is turned off, and the switching device between PWM6 and phase4 is turned on, phase1, phase2, phase3 and phase4 are connected to chip B to power chip B.

[0123] When the switching device between PWM1 and phase1 is turned on, the switching device between PWM2 and phase2 is turned on, the switching device between PWM3 and phase3 is turned on, the switching device between PWM5 and phase3 is turned off, the switching device between PWM4 and phase4 is turned on, and the switching device between PWM6 and phase4 is turned off, phase1, phase2, phase3 and phase4 are connected to chip A to power chip A.

[0124] Of course, in some embodiments, the first output module may not have PWM4, that is, PWM4 does not pass through the switching device with phase4. When the switching device between PWM1 and phase1 is turned on, the switching device between PWM2 and phase2 is turned on, the switching device between PWM3 and phase3 is turned on, the switching device between PWM5 and phase3 is turned off, and the switching device between PWM6 and phase4 is turned off, phase1, phase2, and phase3 are connected to chip A to power chip A.

[0125] Therefore, only four drive voltage converters are needed to make chip A and chip B compatible, which is much easier than Figure 3 In the above method, a driving voltage converter can be reduced, the use space of the PCB layout can be reduced, and the use cost of the driving voltage converter can be reduced.
