The UCC2891/2/3/4 family of PWM controllers is designed to simplify implementation of the various active clamp/reset switching power topologies.
The UCC289x is a peak current-mode, fixedfrequency, high-performance pulse width modulator. It includes the logic and the drive capability for the auxiliary switch with a simple method of programming the critical delays for proper active clamp operation.
The UCC2891/3 includes a 110-V start-up regulator for initial start-up and to provide keep-alive power during stand-by.
Additional features include an internall programmable slope compensation circuit, precise DMAX
limit, and a signle resistor programmable synchronizable oscillator. An accurate line monitoring function also programs the converter's ON and OFF transitions with regard to the bulk input voltage. Along with the UCC2897, this UCC289x family allows the power supply designer to eliminate many of the external components, reducing the size and complexity of the design.
