Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model. Therefore, the following detailed description of the embodiments of the utility model provided in the drawings is not intended to limit the scope of the utility model for which protection is sought, but merely represents the selected embodiments of the utility model. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the utility model.

[0021] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0022] See also Figures 1 to 3 , the utility model discloses a computer CPU and a power supply device thereof, which comprises: a control component and an inductor PL1;

[0023] The start end of the control component is used to connect to an external remote control terminal, the output end of the control component is electrically connected to one end of the inductor PL1, and the other end of the inductor PL1 is used to connect to an external computer CPU, so as to provide a fixed voltage power signal to the external computer CPU;

[0024] Wherein, the control end of the N-MOSFET module of the control component is connected to an external remote control terminal, and the N-MOSFET of the control component is configured to be turned on or off, and the start end and output end of the control component;

[0025] Wherein, the control end of the voltage mode control module of the control component is connected to an external remote control terminal, and the voltage mode control module of the control component is configured to control the size of the power signal provided to the external computer CPU.

[0026] Preferably, the chip model of the control component is MP2961GL.

[0027] In this embodiment, the computer CPU power supply device uses a highly integrated power chip MP2961GL, which only needs to be matched with an inductor and peripheral resistors and capacitors to achieve the same function as the RT6543AGQW solution in the prior art with a simplified circuit to power the CPU.

[0028] The basic working process of the control component is: when the 8th PIN (EN) of the control component receives a high level signal and the 2nd PIN (VIN) is also at a high level, the control component starts to work. The two pairs of N-MOSFETs integrated inside the IC start the working mode of alternating switching of the upper MOS tube and the lower MOS tube, the upper NMOS is responsible for input, and the lower NMOS is responsible for output.

[0029] Then the 11th PIN (SW2) and the 12th PIN (SW1) of the control component will send out a PWM (Pulse e Width Modulation (Pulse Width Modulation) signal, after passing through the inductor PL1, will output a fixed voltage power signal +VCCIN AUX, and after being filtered by the output capacitor, it is transmitted to the CPU to provide a stable power supply for the CPU.

[0030] It can be seen that the power module circuit of the entire computer CPU power supply device is simple and efficient, with few peripheral devices, which is convenient for engineers to design and debug. At the same time, it can greatly reduce costs and increase product competitiveness.

[0032] Table 1

[0033] See also Figure 1 and the above Table 1 (the above Table 1 is a voltage control mode table of the voltage mode control module of the control component provided by the embodiment of the utility model), in this embodiment, the 5th PIN (VID1) and the 6th PIN (VID0) of the control component can jointly determine the voltage of +VCCIN_AUX through the high and low logic levels of the PIN pins themselves to adapt to the requirements of the CPU in different states, and the levels of VID1 and VID0 are controlled by the CPU:

[0034] (1) When the computer is turned off, the CPU is not working. At this time, the CPU will control both VID1 and VID0 to a low level, and the output voltage of +VCCIN_AUX is 0V;

[0035] (2) When the CPU is in the state of retaining the FIVR voltage except the +VCCIN_AUX voltage, the CPU will make VID1 in the low state and VID0 in the high state. At this time, the output voltage of +VCCIN_AUX is 1.1V;

[0036] (3) When the +VCCIN_AUX voltage module of the CPU is in a low current state, the CPU will make VID1 in a high level state and VID0 in a low level state. At this time, the output voltage of +VCCIN_AUX is 1.65V;

[0037] (4) When the +VCCIN_AUX voltage module of the CPU is in a high current state, the CPU will make both VID1 and VID0 in a high level state. At this time, the output voltage of +VCCIN_AUX is 1.8V;

[0038] It can be seen from the above four situations that when the CPU is in different states, the VID1 and VID0 of the control component will be controlled to be at corresponding levels, and the control component will output different +VCCIN_AUX voltages to the CPU through different VID1 and VID0 levels to meet the needs of the CPU, and the two form a good closed system.

[0041] See also Figure 1 And the above Table 2 (the above Table 2 is the output current limiting table provided by an embodiment of the utility model), in this embodiment, when the 16th PIN (MODE2) of the control component is in Floating, each phase of the power supply can support at least 18A load, that is, SW1 and SW2 can each support at least 18A load, and the entire control component can support at least 36A load, which can fully meet the power consumption requirements of Intel's 12th and 13th generation CPUs.

[0042] Preferably, the inductor PL1 is configured to limit current mutations.

[0043] In this embodiment, the inductor PL1 in the DC circuit mainly functions to limit current and filter. When current flows through the inductor, a certain voltage drop will be generated, thereby limiting the rate of increase of the current, that is, limiting the sudden change of the current.

[0044] Preferably, an output capacitor is further included, and the other end of the inductor PL1 is electrically connected to the output capacitor.

[0045] Preferably, the output capacitor is a filter capacitor to remove high-frequency components or low-frequency components in the power signal provided to the external computer CPU.

[0046] In this embodiment, the output capacitor can remove high-frequency components or low-frequency components in the signal, so that the output signal is smoother or noise is removed, thereby improving the stability and performance of the circuit.
