Driver for High Efficiency  
SMPS Topologies  
http://onsemi.com  
The NCP4303A/B is a full featured controller and driver tailored to  
control synchronous rectification circuitry in switch mode power  
supplies. Thanks to its versatility, it can be used in various topologies  
such as flyback, forward and Half Bridge Resonant LLC.  
The combination of externally adjustable minimum on and off times  
helps to fight the ringing induced by the PCB layout and other  
parasitic elements. Therefore, a reliable and noise less operation of the  
SR system is insured.  
The extremely low turn off delay time, high sink current capability  
of the driver and automatic package parasitic inductance  
compensation system allow to maximize synchronous rectification  
MOSFET conduction time that enables further increase of SMPS  
efficiency.
