Abstract:
1. A multiple power supply device, comprising: a power consuming unit, having a power receiving terminal and a plurality of detection terminals, wherein the detection terminals receive a plurality of power good signals respectively, and the power consuming unit outputs a plurality of power control signals according to the power good signals, wherein the power consuming unit is a programmable chip; a plurality of power supply units, for outputting a plurality of working voltages respectively and outputting the power good signals correspondingly when outputting the working voltages; and a plurality of switching units, coupled to the power receiving terminal and respectively coupled to the power supply units for receiving the power control signals from the power consuming unit and the power working voltages from the power supply units, wherein when the power consuming unit is in a working state and one of the power good signals is enabled, the power consuming unit enables the corresponding power control signal, and one of the switching units transmit the corresponding working voltage to the power receiving terminal according to the enabled power control signal; while when the power consuming unit is in a working state and a part of the power good signals are enabled, the power consuming unit enables one of the power control signals corresponding to the enabled power good signals, and one of the switching units transmit the corresponding working voltage to the power receiving terminal according to the enabled power control signal.
