Description

PMP21022 is a low cost bias supply reference design with 12V/850mA output from 120VAC input. This design uses a UCC28722 constant current/constant voltage PWM with primary-side regulation flyback controller to reduce the BOM cost. This design passes class B conducted EMI without applying any common mode choke.

Features
  • 120VAC nominal (102VAC to 138VAC) 50/60Hz input to 12V/0.85A output
  • Pass class B conducted EMI without any common mode choke
  • Test report available
  • PSR flyback
