High Performance Current Mode Controllers General Description UC3842B/3B/4B/5B,UC2842B/3B Package outline The UC3842B/3B/4B/5B, series are high performance fixed frequency current mode controllers. They are specifically designed for Off- Line and dc- to- dc converter applications offering the designer a cost- effective solution with minimal external ponents. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature pensated reference, high gain error amplifier, current sensing parator, and a high current totem pole output ideally suited for driving a power MOSFET. Also included are protective Features consisting of input and reference...
