UC3845B Datasheet High Performance Current Mode Controller

Manufacturer: onsemi

Overview: 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 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.

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

Key Features
