onsemi NCP4318BLCDR2G, 1, Voltage Regulator, 500 kHz 8-Pin, SOIC

The ON Semiconductor NCP4318 is an advanced synchronous rectification (SR) controller for LLC resonant converter with minimum external components. It has two gate driver stages for driving the SR MOSFETs which are rectifying the outputs of the secondary transformer windings. The two gate driver stages have their own Drain and Source sensing inputs and operate independently of each other.

Adaptive minimum turn−on time for noise immunity
SR conduction time increase rate limitation
Multi−level turn−off threshold voltage
Adaptive gate voltage control (10 V, 6 V)
Low operating current (100 A) in green mode
Soft start for 512 switching cycle wi
