Introduction

Ex9610PD is a synchronous rectification switch with an integrated 100V-rated power MOSFET featuring 15mΩ low on-resistance. Designed for the secondary side of AC/DC flyback switching power supply transformers as a replacement for output rectifier diodes, it can significantly improve power conversion efficiency. The integrated high-voltage self-supply function eliminates the need for a transformer auxiliary winding — only a single 1uF external capacitor is required to power the IC, with a self-supply voltage of 7.7V. It can be flexibly placed on either the positive or negative output terminal of the transformer. Ex9610PD controls the turn-on and turn-off of the built-in MOSFET by sensing the VDS voltage. When VDS drops below -350mV, the MOSFET is turned on; the integrated dynamic drive function stabilizes VDS at approximately -40mV. When VDS rises above 0mV, the MOSFET is turned off. The built-in power MOSFET uses SGT MOSFET technology, offering lower gate capacitance for easier fast turn-off, effectively suppressing voltage spikes, reducing voltage stress, and improving reliability. The synchronous rectification switch features fast turn-off capability and supports DCM, QR quasi-resonant, and CCM operating modes.
