The UC3844B UC3845B 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. Also included are protective
