DALLAS (Aug. 16, 2011) – Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced two high-efficiency PWM power supply controllers with integrated, programmable-delay synchronous rectifier control outputs and pre-bias start-up circuitry. The UCC28250 and UCC28950 “green controllers” simplify design and boost efficiency in high-density isolated power supplies for telecommunications, server and industrial systems. The devices support multiple high-frequency topologies, such as half-bridge, full-bridge, interleaved forward and push-pull, that may have stringent pre-bias start-up requirements and support multiple high-efficiency topologies.
