The NCP4306 is high performance driver tailored to control a synchronous rectification MOSFET in switch mode power supplies. Thanks to its high performance drivers and versatility, it can be used in various topologies such as DCM or CCM flyback, quasi resonant flyback, forward and half bridge resonant LLC.

Allows for proper timing of SR MOSFET turn on and turn off
Maximizes conduction time of the MOSFET to increase efficiency
Allows direct connection of CS input to MOSFET drain in flyback applications
Improves performance for applications working in deep CCM
Enters the IC into a low consumption standby mode
Prevents accidental MOSFET turn on or turn off due to ringing
Enhanced Operation for USB-PD Applications
Fast turn off of MOSFET for optimized conduction period
Increased stability coming in and out of Light Load
Wide output operating voltages
