UCC2894DR Description

Short technical summary and product information.

The Texas Instruments UCC2894DR is a high-performance, fixed-frequency pulse width modulator designed for active clamp/reset switching power topologies. It is ideal for Flyback and Forward converters, offering features such as peak current-mode control with cycle-by-cycle current limiting.

 

This PWM controller operates within an 8.5V to 16V input voltage range and features a 1.0MHz synchronizable oscillator. It supports a maximum duty cycle of 70% and includes programmable soft start and slope compensation. The device also provides TrueDrive outputs with 2-A sink and 2-A source capabilities.

 

Designed for applications requiring high efficiency and low EMI/RFI, the UCC2894DR is suitable for SMPS ranging from 150W to 700W. It is available in a 16-SOIC surface mount package.

 

Key features include low output jitter, soft-stop shutdown, and accurate line UV/OV thresholds, simplifying the implementation of complex power supply designs.
