UCC24624 Dual-Channel Synchronous Rectifier Controller

The UCC24624 high-performance synchronous rectifier (SR) controller is dedicated for LLC resonant converters to replace the lossy diode output rectifiers with SR MOSFETs and improve the overall system efficiency. The UCC24624 SR controller uses drain-to-source voltage sensing method to achieve on .

UCC24624 Features

* 230-V VD pins rating

* 23-ns turn-off delay to support LLC operating above resonant frequency and up to 625-kHz switching frequency

* Proportional gate drive to extend the SR conduction time

* Adjustable turn-off threshold for minimum body diode conduction
