ONSEMI NCP4318BLCDR2G LLC Resonant Converter Controller

The NCP4318 is an advanced synchronous rectifier controller designed for LLC resonant converters, featuring adaptive dead time, body diode conduction minimization, and high efficiency. It drives two independent gate driver stages for SR MOSFETs, with fast delay times and robust protection features including primary shutdown and abnormal drain sensing. Its low operating current in green mode and wide supply voltage range make it ideal for high power density adapters, LED lighting, and telecom power supplies. Compact SOIC-8 package ensures easy integration into space-constrained systems, enhancing overall system reliability and performance.
