DATA SHEET www.onsemi.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.
