The UCC28951PWR from Texas Instruments is a phase-shifted full-bridge controller designed for wide input voltage range applications. It offers enhanced zero-voltage switching (ZVS) capabilities and direct synchronous rectifier (SR) control, contributing to improved light-load efficiency through modes like Burst mode and Discontinuous Conduction Mode (DCM).
This controller supports average or peak current mode control with programmable slope compensation, alongside voltage-mode control. Key features include closed-loop soft-start, an enable function, and programmable switching frequency up to 1 MHz with bidirectional synchronization. For protection, it incorporates cycle-by-cycle current limit protection with hiccup mode support and VDD undervoltage lockout.
The UCC28951PWR is housed in a 24-TSSOP package suitable for surface mounting. It operates over a wide temperature range of -40°C to 125°C (TJ), making it suitable for various demanding environments. The device requires an input voltage between 8V and 17V and offers up to 6 outputs with a single output phase.
