UCC28950TPWRQ1 Description

Short technical summary and product information.

The Texas Instruments UCC28950TPWRQ1 is an automotive-qualified, phase-shifted, full-bridge PWM controller designed for wide-input voltage range applications. It supports an input voltage range from 8V to 17V and features adjustable switching frequencies up to 1MHz with bidirectional synchronization.

 

Key electrical features include current limiting with hiccup mode support, dead time control, enable function, and soft start. The controller also incorporates light-load efficiency management, including burst mode operation and discontinuous conduction mode (DCM) with dynamic SR on/off control. It supports both average- or peak-current mode control with programmable slope compensation and voltage-mode control.

 

Packaged in a 24-TSSOP, the UCC28950TPWRQ1 is suitable for surface mount applications. It operates within a temperature range of -40°C to 105°C (TA). The device is AEC-Q100 qualified, indicating its suitability for automotive environments.
