Description

DESCRIPTION
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, fixed
frequency, 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.
FEATURES
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
APPLICATIONS
150-W to 700-W SMPS
High-Efficiency, Low EMI/RFI Off-Line or DC/DC Converters
Server, 48-V Telecom, Datacom
High Power Adapter, LCD-TV and PDP-TV
