UCC2893PWR Description

Short technical summary and product information.

The UCC2893PWR from Texas Instruments is a high-performance, fixed-frequency pulse width modulator designed for active clamp/reset switching power topologies. It operates within an 8.5V to 16V input voltage range and features a maximum duty cycle of 70% at a frequency of 250kHz.

 

Key features include peak current-mode control with cycle-by-cycle current limiting, programmable slope compensation, and a programmable soft start function. The device also offers low output jitter and soft-stop shutdown capabilities for both main and auxiliary switches. It is ideal for applications such as active clamp/reset forward, flyback converters, and general DC/DC converters.

 

This controller is housed in a 16-TSSOP package suitable for surface mounting. Its design simplifies the implementation of active clamp circuits, reducing external component count and design complexity for power supply engineers. The UCC2893PWR is suitable for SMPS applications ranging from 150W to 700W, including server, telecom, and high power adapter designs.
