Design files

Overview

This design is a 100kHz FBPS converter working in voltage mode. It supports 400Vdc..750Vdc input voltage range and provides 24V/12A regulated. TI's UCC28950 part enables high efficiency at high input voltage.

Features
  • Over 92% efficiency at full load
  • High input voltage
  • 250W phase shifted fullbridge
  • Wide high input voltage range 400Vdc to 750Vdc
  • Provides synchronous rectification w/ efficient voltage doubler
