Overview

The UCC28250EVM-564 is a fully assembled and tested circuit for evaluating the UCC28250 Advanced PWM Controller with Pre-Bias Operation. The UCC28250EVM-564 comprises a symmetrical half bridge DC-DC converter which converts a 36V to 75V DC input to a 3.3V DC output with 100W maximum output power.

Features
  • Pre-biased Startup
  • Synchronous Rectifier Control Outputs with Programmable Delays (Including Zero Delay Support)
  • Voltage Mode Control with Input Voltage Feed-Forward or Current Mode Control
  • Primary or Secondary-Side Control
  • 3.3-V, 1.5% Accurate Reference Output
  • 1-MHz Capable Switching Frequency
  • 1% Accurate Cycle-by-Cycle Over Current Protection with Matched Duty Cycle Outputs
  • Programmable Soft-Start and Hiccup Restart Timer
AC/DC & DC/DC controllers (external FET)
