[0048] First, a description is given of the regulator device in the first embodiment. figure 1 is a block diagram showing the configuration of the regulator device. like figure 1 As shown, the regulator device 100 is provided with a power input terminal 102, a first power output terminal 104, a second power output terminal 106, a plurality (three) of regulators 110A, 110B and 110C, and a controller IC (Integrated Circuit) 140 . In addition, regulator device 100 is provided with coils 152 and 162 , capacitors 154 and 164 , ammeters 156 and 166 and dummy load 400 .

[0049] The power input terminal 102 is a terminal to which a voltage (Vin) supplied from outside the regulator device 100 is applied. A DC voltage of, for example, 5-12 (V) is applied to the power input terminal 102 . The DC voltage applied to the power input terminal 102 is converted into a DC voltage to be output from the first power output terminal 104 or the second power output terminal 106 at a predetermine...

[0095] Then, the regulator device 100 in the second embodiment will be described. The regulator device 100 in the second embodiment is similar to the regulator device 100 in the first embodiment except for having a different register configuration in the memory 142 and processing related to the register configuration. Therefore, only parts different from the first embodiment will be described, and descriptions of the remaining configurations similar to the first embodiment will be omitted.

[0096] The register configuration in the memory 142 of the regulator device 100 in the second embodiment will be described below. Figure 9 is a schematic diagram showing an example of register construction. Figure 10 is a schematic diagram showing an example of the configuration of the output current register. Figure 11 is a schematic diagram showing an example of the register configuration of the selection / measurement regulator. Figure 12 is a schematic diagram showing an example o...

[0111] Then, the regulator device 100 in the third embodiment will be described. The regulator device 100 in the third embodiment is similar to the regulator device 100 in the first embodiment except for having a different register configuration in the memory 142 and processing related to the register configuration. Therefore, only parts different from the first embodiment will be described, and descriptions of the remaining configurations similar to the first embodiment will be omitted.

[0112] The register configuration in the memory 142 of the regulator device 100 in the third embodiment will be described below. Figure 14 is a schematic diagram showing an example of register construction. Figure 15 is a schematic diagram showing an example of the configuration of the temperature register.

[0113] like Figure 14 As shown, the registers in memory 142 may be of a 24-bit configuration D0 through D23. Because registers D0 to D19 are similar to Figure 9 The above regis...

Abstract

A regulator device includes: a plurality of regulators that are equipped in parallel between a power input terminal and a power output terminal and converts a power inputted from the power input terminal to output to the power output terminal,a dummy load circuit that is coupled to a power output system different from a power output system to the respective power output terminal of the plurality of regulators,a selector that selects a regulator to carry out an output to the power output terminal and a regulator to carry out an output to the dummy load circuit among the plurality of regulators,and a controller that obtains conversion efficiency characteristic information representing a characteristic of power conversion efficiency relative to a current flowing in the dummy load circuit for the regulator to carry out an output to the dummy load circuit.

Description

technical field [0001] The embodiments discussed herein relate to regulator devices. Background technique [0002] Generally, for wireless communication devices such as mobile phones or information processing devices such as PCs (Personal Computers) and servers, regulators for power conversion are used, which convert input power into desired output power. [0003] As wireless communication devices and information processing devices have become more powerful in terms of performance and functions in recent years, they tend to have gradually increasing peak load currents while requiring stable power supply over a long period of time by reducing power consumption. [0004] Meanwhile, there are various types of regulators according to differences in rated current or rated voltage, for example, and power conversion efficiency characteristics with respect to output current values ​​differ depending on the types of regulators. [0005] For example, even when items in the same serie...
