The UCC28950 from Texas Instruments is a phase-shifted full-bridge controller that provides advanced control for the output stage, including active control of the synchronous rectifier (SR). This controller ensures zero-voltage switching (ZVS) over a wide range of operating conditions, maximizing system efficiency.
Key electrical features include a programmable switching frequency up to 1 MHz with bidirectional synchronization and a cycle-by-cycle current limit protection with hiccup mode support, accurate to ±3%. It also features a low start-up current of 150µA and VDD undervoltage lockout.
The device operates across a wide temperature range from -40°C to +125°C. It is available in a 24-pin TSSOP package with dimensions of 7.80mm x 4.40mm. The UCC28950 is suitable for applications such as server power supplies, industrial power systems, and high-density power architectures.
