US 2014/0006832 A1 · POWER SUPPLY CIRCUIT AND HARD DISK BACKPLANE USING SAME

Abstract

A power supply circuit includes a first power input terminal, a second power input terminal, a first switch circuit, and a first switch controller. The first and second power input terminals are configured to receive a first voltage and output the first voltage to supply a first hard disk group and a second hard disk group. The first switch circuit is coupled between the first power input terminal and the second power input terminal. The first switch controller switches on or switches off the first switch circuit. When the first switch circuit is switched on, the first power input terminal is connected to the second power input terminal. When the first switch circuit is switched off, the first power input terminal is disconnected from the second power input terminal.
