NCP1566 Active Clamp Forward Controller:

Value Proposition:

The NCP1566 is a highly integrated dual-mode active-clamp PWM controller  to implement an isolated active clamp forward or asymmetric half-bridge converter.  It which can be configured in either voltage mode control with input voltage feed-forward or peak current mode control. Peak current mode control may be implemented with input voltage feedforward as well.
