More Information
The UCC28251 PWM controller is designed for high power density applications that may have stringent prebiased startup requirements. The UCC28251s integrated synchronous rectifier control outputs target high efficiency and high performance topologies such as half-bridge, full-bridge, interleaved forward, and push-pull. The UCC27210 half bridge drivers and UCC2752x MOSFET drivers used in conjunction with the UCC28251 provide a complete power converter solution.
