This reference design is a high-density, 60-W 115-VAC input power supply for USB Type-C applications that uses the UCC28782 active clamp flyback controller, LMG2610 integrated GaN half-bridge and UCC24612 synchronous rectifier driver. The maximum power rating is 60 W at 20-V or 15-V output, 54 W at 9-V output and 30 W at 5-V output. This design reaches a peak efficiency of 94.8%. The design has dimensions of 1.5 inch by 3.35 inch by 1 inch (37.5 mm by 85 mm by 25 mm).
