NCP4318 Overview
Advanced Synchronous Rectifier Controller for LLC Resonant Converter NCP4318 NCP4318 is an advanced synchronous rectification (SR) controller for LLC resonant converter with minimum external ponents. It has two gate drivers for driving the SR MOSFETs rectifying the outputs of the secondary transformer windings. The two gate drivers have their own drain and source sensing pins and operate independently of each other.
