Cantor Colburn LLP
Insulation-type synchronous DC/DC converter
The synchronous rectifier controller is provided at the secondary side of the insulation-type synchronous DC/DC converter and controls the synchronous rectifier transistor. The controller is coupled to the output of the feedback photo coupler and drives the switching transistor according to the feedback signal. The synchronous rectifier controller includes a driver circuit and an abnormal detection circuit and is configured as a single module. The driver circuit drives the synchronous rectifier transistor. The abnormal detection circuit detects an abnormal condition in the secondary side of the DC/DC converter. FAIL terminal is coupled to notify outside of an occurrence of the abnormal condition.
