SLUSBD8E – FEBRUARY 2013 – REVISED DECEMBER 2014 UCC28251 Advanced PWM Controller With Prebias Operation
1 Features 3 Description 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 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. 1 Prebiased Startup
