Description:

Active Clamp Voltage Mode PWM Controller

Features

* such as line UV/OV protection, soft
* start, single resistor programmable (high) frequency oscillator, line voltage feedforward, dual mode overcurrent protection and maximum duty cycle control, allow converter optimization at minimal cost. Compared to a traditional forward converter, an NCP128

Applications

* The NCP1280 provides a highly integrated solution for off
* line power supplies requiring high
* efficiency and low parts count. This voltage mode controller provides control outputs for driving a forward converter primary MOSFET and an auxiliary MOSFET for active clamp circuit. The sec
