Description

The PMP20869 is a low cost bias supply reference design with 12V/1.5A output from 120VAC input. This design uses a UCC28700 constant current/constant voltage PWM with primary-side regulation flyback controller and single layer PCB to reduce the overall BOM cost. 

Features
  • 120VAC nominal (102VAC to 138VAC) 50/60Hz input to 12V/1.5A output
  • Conduction EMI tested
  • Single layer PCB design
  • PSR flyback
  • Test report available
