Description
This UCC28730 based upside-down buck design converts a universal line input to a non-isolated 80V/50W output. An additional 12V/600mW output is produced using a UCC28880. The design achieves over 93% efficiency and consumes less than 50mW of standby power.
Features
- Universal line input 85VAC - 265VAC
- Over 93% efficiency for low nad high line at 50W
- Low standby power consumption <50mW
- 2 layer board, 1 oz copper weight, dimensions are 2.1in x 2.8in x 1in
- Low cost design
