摘要:
The present invention relates to a synchronous rectifying type power supply circuit as a switching power supply having a control circuit including a rectifying FET for synchronous rectifying operation in the secondary side of a transformer. A commutating FET can be structured by providing a switching control circuit that is connected to a tertiary coil provided to the transformer to conduct ON/OFF operation of the rectifying FET and commutating FET.
