com Secondary Side Synchronous Rectification Driver for High Efficiency SMPS Topologies NCP4306 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 s...
