Description
The UCC2897A PWM controller simplifies implementation of the various active clamp/reset and synchronous rectifier switching power topologies. The UCC2897A is a peak current-mode, fixedfrequency, high-performance pulse width modulator. It includes the logic and the drive capability for the P-channel auxiliary switch along with a simple method of programming the critical delays for proper active clamp operation. Features include an internal programmable slope compensation circuit, precise DMAX limit, and a synchronizable oscillator with an internal timing capacitor. An accurate line monitoring function also programs the converter’s ON and OFF transitions with regard to the bulk input voltage, VIN. The UCC2897A adds a second level hiccup mode current sense threshold, bi-directional synchronization and input overvoltage protection functionalities. View All Description in Datasheet |
