UC2843A Datasheet High Performance Current Mode Controllers

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: 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 components. These integrated circuits feature a trimmed oscillator for precise duty cycle control, a temperature compensated reference, high gain error amplifier, current sensing comparator, and a high current totem pole output ideally suited for driving a power MOSFET.

This datasheet includes multiple variants, all published together in a single manufacturer document.
