UCC28950PWR Description

Short technical summary and product information.

The UCC28950PWR from Texas Instruments is an enhanced phase-shifted controller designed for high-performance power systems. It features Green Phase-Shifted Full-Bridge control with Synchronous Rectification, offering enhanced wide-range resonant zero voltage switching (ZVS) capability.

 

This controller supports a wide input voltage range of 8V to 17V and programmable switching frequencies up to 1MHz. Key control features include dead time control, enable, frequency control, and soft start. It also incorporates light-load efficiency management, including burst mode operation and discontinuous conduction mode (DCM) with dynamic SR on/off control.

 

The UCC28950PWR is housed in a 24-TSSOP package suitable for surface mounting. Its operating temperature range is -40°C to 125°C (TJ). The controller is designed for applications such as phase-shifted full-bridge converters, server power supplies, datacom, telecom, and industrial power systems.

 

Additional features include cycle-by-cycle current limit protection with hiccup mode support and a 150µA start-up current. The device naturally handles pre-biased start-up with DCM mode.
