Datasheet Summary
Advanced Synchronous Rectifier Controller for LLC Resonant Converter
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. The advanced adaptive dead time control pensates the voltage across parasitic inductance to minimize the body diode conduction and maximize the system efficiency. The advanced turn- off control algorithm allows stable SR operation over entire load range. NCP4318 has two...
