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.
