Abstract

A power unit comprises a power connector for, upon the reception of supplied power, supplying the power to an exterior part of the power connector, a plurality of OBPs (223_31-223_35) which each perform processing upon the reception of an applied voltage, which supply power by applying voltage to a plurality of processing devices (221_31-221_35) including different kinds of expected applied voltages, and to which power is supplied directly or indirectly from the power connecter, and a power control unit (224_3) which increases or decreases power which is supplied to the processing device by each OBP according to the size of a processing load in the processing device and increases or decreases the power according to the size of a processing load in a processing device having an applied voltage which is different from that of the processing device.

Description

technical field [0001] The present invention relates to a power supply device for supplying electric power to a processing device, and electronic equipment equipped with such a power supply device. Background technique [0002] Conventionally, electronic equipment such as communication equipment and server equipment has a power supply device that supplies power to ICs and the like that execute various processes. In this power supply device, it is necessary to always supply stable electric power, and in particular, it is necessary to adjust the output voltage to an IC or the like to be constant. [0003] figure 1 This is a schematic configuration diagram of a power supply unit that supplies power to electronic equipment. [0004] Should figure 1 The illustrated power supply device 10 is a power supply device of an analog control method in which an output voltage to an IC or the like is controlled using an analog device such as an amplifier or a comparator. [0005] The po...
