资 源 简 介
The UCC28250 PWM controller is designed for high power density applicaTIons that may have stringent pre-biased startup requirements. The UCC28250’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 UCC27200 half bridge drivers and UCC2732X MOSFET drivers used in conjuncTIon with the UCC28250 provide a complete power converter soluTIon.
Externally programmable soft-start, used in conjunction with an internal pre-biased startup circuit, allows the controller to gradually reach a steady-state operating point under all output conditions. The UCC28250 can be configured for primary or secondary-side control and either voltage or current mode control can be implemented.
