UC2842B, UC2843B
The UC3842B, UC3843B series are high performance fixed frequency current mode controllers. They are specifically designed for Off- Line and DC- 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...
