Order this document by UC3842A/D UC3842A, 43A UC2842A, 43A High Performance Current Mode Controllers The UC3842A, UC3843A series of high performance fixed frequency current mode controllers 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 undervoltage...
