UCC2893DR Description

Short technical summary and product information.

The UCC2893DR from Texas Instruments is a high-performance, fixed-frequency, peak current-mode pulse width modulator. It is designed to simplify the implementation of active clamp/reset switching power topologies such as active-clamp forward and flyback converters.

 

Key electrical features include an operating voltage range of 8.5V to 16V, a maximum duty cycle of 70%, and a synchronizable oscillator operating at 250kHz. It offers programmable features like soft start, slope compensation, and deadtime control for the auxiliary switch, along with cycle-by-cycle current limiting. The device provides TrueDrive outputs with 2-A sink and 2-A source capabilities.

 

This controller is suitable for applications ranging from 150-W to 700-W SMPS, including server, 48-V telecom, datacom, high power adapters, and display power supplies. It is designed for high efficiency and low EMI/RFI.

 

The UCC2893DR is available in a 16-SOIC package and is designed for surface mount applications. It operates within a temperature range of -40°C to 85°C.
