Product Summary

The UCC2897APW is a PWM controller simplifies implementation of the various active clamp/reset and synchronous rectifier switching power topologies. The UCC2897APW is a peak current-mode, fixed-frequency,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. The applications of the UCC2897APW are (1)High-Efficiency DC/DC Power Supplies ; (2)Server Power, 48-VTelecom, Datacom, and 42-V Automotive Applications.
