Datasheet Summary
High Performance Current Mode Controllers
UC3844B, UC3845B, UC2844B, UC2845B
The UC3844B, UC3845B 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 an oscillator, 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 lockouts each with hysteresis, cycle- by- cycle current limiting, a...
