PMP20339 Reference Design

Texas Instruments

85VAC to 264VAC Input: 12V/450mA and 5V/50mA Dual Output Bias Supply Reference Design

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.
