NCP4302
Secondary Side
Synchronous Flyback
Controller
The NCP4302 is a full featured controller and driver that provide all
the control and protection functions necessary for implementing a
synchronous rectifier operation in a flyback converter. With the use of

the NCP4302, the space conscious flyback applications such as
Adaptors, chargers, set top boxes can achieve significant efficiency
improvements at minimal extra cost. In addition to the synchronous
rectifier control, the IC incorporates an accurate TL431 type shunt
regulator, current monitoring circuit and optocoupler driver to provide
a single IC secondary solution. The NCP4302 works with any type of
flyback topology (continuous mode, Quasi ? resonant mode or
