Description

The PMP20339 is a low cost bias supply reference design with 12V/450mA and 5V/50mA outputs from 120VAC input. A dual-output flyback converter with UCC28700 primary-side regulation controller is used to generate 12V and 5V outputs. Single layer PCB is applied to reduce the overall BOM cost.

Features
  • 85VAC to 264VAC, 50/60Hz input to 12V/450mA and 5V/50mA outputs
  • Less than 35°C temperature rise on all parts
  • Single layer PCB design
  • Dual output flyback with primary-side regulation (PSR)
  • Test report available
