SECONDARY SIDE CONTROLLED CONTROL CIRCUIT FOR POWER CONVERTER WITH SYNCHRONOUS RECTIFIER

摘要

A secondary side controlled control circuit for power converter with synchronous rectifier is provided. The secondary side controlled control circuit comprises a primary side controller and a secondary side controller. The primary side controller generates a primary side switching signal for switching a primary side switch of the power converter. The secondary side controller generates a secondary side switching signal for switching a switch of the synchronous rectifier of the power converter. The secondary side controller generates a primary side control signal to control the primary side controller for controlling the primary side switching signal.
