3.6-W AC/DC coupled inductor buck reference design
Description
This reference design is a non-isolated AC/DC power supply design using the UCC28704 PSR controller to implement a high-voltage buck converter. The converter provides 6 V at 600 mA from an AC input of 100 VAC to 132 VAC. The design uses a coupled inductor to provide a 12-V supply voltage to the controller: eliminating the need for a separate bias supply. This design is one layer: compact and thermally efficient.
Features
- Non-isolated AC/DC 6-V/0.6-A buck converterLess than 45-degrees Celsius in temperature rise on all partsUses coupled inductor to provide controller bias supplyOne layer: compact board size of 2.8 inches by 1.2 inches by 0.5 inches
