Overview

NCP81178 Secondary Synchronous Rectifier Driver for Forward Converters The NCP81178 is a secondary−side synchronous rectifier driver designed for isolated power converters, especially actively clamped forward and fly−back, and asymmetric half−bridge converters.
The NCP81178 drives two N−channel MOSFETs on the secondary side in a complementary manner.
It accepts a PWM input signal derived from the secondary winding or an auxiliary winding on the main power transformer.
It can also take a PWM signal from the primary−side controller through a pulse transformer or other isolators.
Features • N−Channel Synchronous Rectifier MOSFET Driver • PWM Input Derived from a Winding on the Main Transformer ...
