Datasheet Summary
High Performance Current Mode Controllers
The NCV3843BV is a high performance fixed frequency current mode controller. 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 input and reference undervoltage lockouts each with hysteresis, cycle- by- cycle current limiting,...
