Product Overview
The UCC2897APW is a Pulse Width Modulation (PWM) Controller simplifies implementation of the various active clamp or reset and synchronous rectifier switching power topologies. The UCC2897A is a peak current-mode fixed-frequency high-performance pulse width modulator. The controller 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 ON and OFF transitions of the converter with regard to the bulk input voltage, VIN. It adds a second-level hiccup-mode current-sense threshold, bidirectional synchronization and input-overvoltage protection functionalities.
- Low-output jitter
- Soft-stop shutdown of MAIN and AUX
- Ideal for active-clamp, reset-forward, flyback and synchronous rectifier
- Peak current-mode control with 0.5V Cycle-by-cycle current limiting
- Trimmed internal-bandgap reference for accurate line UV and line OV threshold
- Programmable slope compensation
- High-performance 1MHz Synchronizable oscillator with internal timing capacitor
- Precise programmable maximum duty cycle
- Green product and no Sb/Br
Applications
Power Management, Automotive, Communications & Networking
