NCP1282 Overview
NCP1282 High Performance Active Clamp/Reset PWM Controller Featuring 500 V Startup The NCP1282 is a voltage mode controller designed for ac- dc or dc- dc converters requiring high- efficiency and low parts count. This controller incorporates two in phase outputs with an overlap delay to prevent simultaneous conduction and facilitates soft switching. The main output is designed for driving a forward converter primary...
