 The NCP4307 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, active clamp flyback and forward.  Self-supply capability and dual VCC pin option optimizes designs for wide VOUT range applications, such as USB PD, and can be configured for high side or low side operation.
特性   优势
