Reviews (1)

The UC3844B, UC3845B series are controllers for the high performance fixed frequency current mode. They are specifically designed for applications with off-line and dc-to - dc converters that give the designer a cost-effective solution with minimal external components. These built-in circuits feature an oscillator, temperature-compensated reference, high-gain error amplifier, current comparator of sensing.
