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.
