UCC28950QPWRQ1-Automotive 8V to 20V Full-Bridge, Phase-Shifted PWM Controller with Synchronous Rectification

The UCC28950-Q1 enhanced phase-shifted controller builds upon Texas Instruments’ industry-standard UCCx895 phase-shifted controller family with enhancements that offer best-in-class efficiency in today’s high-performance power systems. The UCC28950-Q1 implements advanced control of the full bridge along with active control of the synchronous-rectifier output stage.

The primary-side signals allow programmable delays to ensure ZVS operation over wide load-current and input-voltage ranges, while the load current naturally tunes the secondary-side switching delays of the synchronous rectifiers, maximizing overall system efficiency.

The UCC28950-Q1 also offers multiple light-load management features, including burst mode and dynamic SR on/off control when transitioning in and out of discontinuous-current-mode (DCM) operation, ensuring ZVS operation is extended down to much lighter loads.

In addition, the UCC28950-Q1 includes support for peak current along with voltage-mode control, programmable switching frequency up to 1 MHz, and a wide set of protection features including cycle-by-cycle current limit, UVLO, and thermal shutdown. It is easy to arrange 90-degree phase-shifted interleaved synchronized operation between two converters.

The UCC28950-Q1 is available in a TSSOP-24 package.
