UCC28251 Datasheet (Texas Instruments)

UCC28251, PWM Controller

The UCC28251 PWM controller is designed for high power density applications that may have stringent prebiased startup requirements.

The UCC28251’s integrated synchronous rectifier control outputs target high efficiency and high performance topologies such as half-bridge, full-bridge, interleaved for
