Abstract:
A synchronous rectifier circuit and a multi-output power supply device using the same include a semiconductor switch to control a current flow of the synchronous rectifier circuit, and a switching controller to control the semiconductor switch according to a synchronous rectification control signal and an output control signal generated by feeding back the output voltage of the synchronous rectifier circuit. The synchronous rectifier circuit can control an output voltage, decrease power loss so as to increase the efficiency of the synchronous rectifier circuit, and decrease the cost of the synchronous rectifier circuit.
