Overview

This design uses low cost primary side regulation (PSR) IC UCC28722 with a bipolar transistor for ultra-wide input range applications (85VAC to 528VAC). Two outputs with separated grounds, 5V/0.3A and 16.5V/0.1A are generated.

Features
  • Ultra-wide AC input range: 85VAC-528VAC
  • Dual Output with separated grounds, 5V/0.3A and 16.5V/0.1A
  • 3W Maximum output power rating at efficiency of 63.6% at 85Vac, 61.7% at 528Vac
  • Low cost, 800V bipolar transistor as primary switch for Flyback converter
  • Total 18% output cross-regulation on 5V rail, from no load to full-load
  • Total 13% output cross-regulation on 15V rail, from no load to full-load
