UCC28250EVM-564 Products

The UCC28250EVM-564 PWM controller is designed for high power density applications that may havestringent prebiased start-up requirements. The integrated synchronous rectifier control outputstarget 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 driversused in conjunction with the UCC28250EVM-564 provide a complete power converter solution.

Externally programmable soft-start, used in conjunction with an internal prebiasedstart-up circuit, allows the controller to gradually reach a steady-state operating point under alloutput conditions. The UCC28250EVM-564 can be configured for primary or secondary-side control and eithervoltage or current mode control can be implemented.

The oscillator operates at frequencies up to 2 MHz, and can be synchronized to anexternal clock. Input voltage feedforward, cycle-by-cycle current limit, and a programmable hiccuptimer allow the system to stay within a safe operation range. Input voltage, output voltage andtemperature protection can be implemented. Dead time between primary-side switch and secondary-sidesynchronous rectifiers can be independently programmed.
