15-W opto-regulated multi-output flyback converter reference design for auxiliary supply

Description

This reference design is an isolated opto-regulated: multi-output: 15-W flyback converter. Both 28-V and 7-V outputs are contributing to the voltage regulation on secondary side: while a third output (14 V at 100 mA) is referenced to the primary side ground. This converter has low stand-by power: between 45 mW and 61 mW in the whole Vin range: and has good efficiency at full load (88.8% to 89.6%).

Features
  • 89% peak efficiency and less than 61 mW stand-by lossMultiple-output - 28 V/500 mA and 7 V/50 mA at secondary: 14 V/100 mA at primaryTypically suitable for bias supply in AC/DC converters with universal-mains and PFC boost
Applications
  • Display panel for TV
  • Standalone avionics PFC
  • SMPS power supply for TV
  • Video conference system
