12-V/30-mA output: high-efficiency neutral-less upside-down buck AC/DC power supply reference design
Description
This reference design uses the UCC28910 in an upside-down buck topology to make a 12-V output capable of 30-mA loading from a 120-Vac input. The design achieves more than 70% efficiency at full loading. All components are placed on one side of the board to reduce assembly complexity and cost. The overall board dimensions are 1.35 inches by 1.35 inches with a max height of 0.3 inches (excluding test points). The floating output stays within 1% regulation across loading conditions.
