Design files

Overview

This design is a high voltage flyback for 200Vdc…1000Vdc input voltage which provides 6.5V/3A regulated and 23V/0.5A unregulated (clamped to 27V). TIs UCC28610 Quasi Resonant controller enables a high efficiency, even at high input voltage

Features
  • Provides 25V and 6.5V outputs Non-Isolated
  • Over 84% efficiency at full load
  • Ultra wide high voltage range 200Vdc to 1000Vdc
