UC3844D Datasheet High Performance Current Mode Controllers

Manufacturer: Motorola Semiconductor (now NXP Semiconductors)

Overview: Order this document by UC3844/D UC3844, 45 UC2844, 45 High Performance Current Mode Controllers The UC3844, UC3845 series are high performance fixed frequency current mode controllers. They 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 an oscillator, 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.
