Abstract

A switching power supply module and a memory storage device are disclosed. The switching power supply module includes a first voltage regulation circuit, a second voltage regulation circuit, a switch circuit and a control circuit. The first voltage regulation circuit is configured to regulate an original power as a first power. The second voltage regulation circuit is configured to regulate the original power as a second power. The control circuit is configured to control the switch circuit to conduct a first power supply path under a first status to provide the first power to the first power supply target. The control circuit is further configured to control the switch circuit to conduct a second power supply path under a second status to provide the second power to the second power supply target.
