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

discontinuous mode) – providing a high level of versatility.
