UCC2897ARGPR Description

The UCC2897ARGPR is a high-performance peak current-mode fixed frequency pulse-width modulator. The controller has the logic and drive capability for the P-channel auxiliary switch, as well as a simple mechanism for programming the essential delays required for optimal active-clamp operation.

UCC2897ARGPR Features

? With 0.5-V cycle-by-cycle current limiting, peak current-mode control is possible.

? TrueDriveTM outputs: 2-A sink, 2-A source

? Internal bandgap reference has been trimmed for precise line UV and line OV thresholds.

? Slope adjustment that can be programmed

UCC2897ARGPR Applications

? High-efficiency DC-to-DC power converters

? 48-volt telecom, datacom, and 42-volt automotive applications
