The Texas Instruments UCC28250 advanced PWM controller with pre-bias operation is designed for high power density applications that have stringent pre-biased startup requirements. The integrated synchronous rectifier control outputs target high efficiency and high performance topologies such as half-bridge, full-bridge, interleaved forward, and push-pull. The TI UCC28250 PWM controller features voltage mode control with input voltage feed-forward or current mode control. This TI PWM controller provides primary or secondary-side control and 3.3v, 1.5% accurate reference output. The UCC28250 is designed for use in a variety of applications, including telecom and data-com power, wireless base station power, server power, and industrial power systems.
