    Products Detail

    The UCC2891/2/3/4 family of PWM controllers is designed to simplify implementation of the various active clamp/reset switching power topologies. 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 internal programmable slope compensation circuit, precise D MAX limit, and a single 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.

    Key Features

    • Low Output Jitter, Soft-Stop Shutdown of MAIN and AUX, Ideal for Active Clamp/Reset Forward, Flyback Converters, Provides Complementary Auxiliary Driver with Programmable Deadtime (Turn-On Delay) between AUX and MAIN Switches, Peak Current-Mode Control with Cycle-by-Cycle Current Limiting, 110-V Input Startup Regulator on UCC2891/3, TrueDrive 2-A Sink, 2-A Source Outputs, Accurate Line UV and Line OV Threshold, Programmable Slope Compensation, 1.0-MHz Synchronizable Oscillator, Precise Programmable Maximum Duty Cycle, Programmable Soft Start
