NCP4306  
Secondary Side  
Synchronous Rectification  
Driver for High Efficiency  
SMPS Topologies  
www.onsemi.com  
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.  
The combination of externally or fixed adjustable minimum  
off-time and on-time blanking periods helps to fight the ringing  
induced by the PCB layout and other parasitic elements. A reliable and  
noise less operation of the SR system is insured due to the Self  
Synchronization feature. The NCP4306 also utilizes Kelvin  
connection of the driver to the MOSFET to achieve high efficiency  
operation at full load and utilizes a light load detection architecture to  
achieve high efficiency at light load.

The precise turn−off threshold, extremely low turn−off delay time  
and high sink current capability of the driver allow the maximum  
synchronous rectification MOSFET conduction time and enables  
maximum SMPS efficiency. The high accuracy driver and 5 V gate  
clamp enables the use of GaN MOSFETs.
