The UCC28951-Q1 enhanced phase-shifted full bridge controller builds upon Texas Instrument’s industry standard UCx895 controller family with enhancements that offer best in class efficiency in today’s high performance power systems. The UCC28951-Q1 implements advanced control of the full-bridge along with active control of the synchronous rectifier (SR) output stage.
●Programmable delays ensure ZVS operation over a wide range of operating conditions, while the load current naturally tunes the switching delays of the secondary-side SRs, maximizing overall system efficiency.
●The UCC28951-Q1 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.
●In addition, the UCC28951-Q1 includes support for current or 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.
●The UCC28951-Q1 is available in TSSOP-24 package and is RoHS compliant.
