UCC2891 CURRENT MODE ACTIVE CLAM
***ark
Pulse Width Modulation (PWM) Controller IC; Output Current Max:2A; Frequency:1000kHz; Supply Voltage Min:8.5V; No. of Pins:16; Operating Temperature Range:-40°C to +85°C; Control Mode:Current; Number of PWM Outputs:1 ;RoHS Compliant: Yes
***AS INSTR
The UCC2891/2/3/4 family of PWM controllers is designed to simplify implementation of the various active clamp/reset switching power topologies.
***NS
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.
***OMO Electronic
The UCC2891/3 includes a 110-V start-up regulator for initial start-up and to provide keep-alive power during stand-by.
***AS INSTR
Additional features include an internal programmable slope compensation circuit, precise DMAX limit, and a single resistor programmable synchronizable oscillator. An accurate line monitoring function also programs the converter\x92s 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.
UCC2891x High-Voltage Flyback Switcher
OMO Electronic UCC2891x High-Voltage Flyback Switcher is dedicated to isolated flyback power supplies and provides output voltage and current regulation without the use of an optical coupler. The device incorporates a 700V power FET and a controller that processes operating information from the auxiliary flyback winding and from the power FET to provide precise output voltage and current control. The integrated high-voltage current source for startup that is switched off during device operation and the controller current consumption that is dynamically adjusted, allows very low stand-by power. Control algorithms in the UCC2891x, combining switching frequency and peak primary current modulation, allow operating efficiencies to meet or exceed applicable standards. Discontinuous conduction mode (DCM) with valley switching is used to reduce switching losses. The maximum switching frequency is 115kHz. Protection features help to keep secondary and primary component stress levels in check across the operating range.
