Current Mode PWM Controller for Both Forward and Flyback Converters
NCP1212 is a high performance current mode PWM controller specifically designed for off−line and DC−to−DC converter applications. The device requires very few external components and offers designer additional protection for better system reliability. The device features a trimmed oscillator for precise Duty Cycle control, accurate bandgap voltage reference, high gain error amplifier, current sensing comparator and a high current totem pole output gate driver that ideally drives the external power MOSFET.
