Description
The PMP20654 reference design uses Buck converter to convert low line AC input voltage (85Vac to 140Vac) to a 12V/25mA DC output with UCC28880 FET integrated controller. This design passes class B conducted emission test without adding any EMI filter before rectifier.
Features
- 85VAC - 140VAC to 12V/25mA
- Single-layer PCB
- Pass Class B conducted emission test
- Less than 10°C temperature rise at toom temperature
