This reference design is a high density USB adapter that uses the UCC28780 active clamp flyback controller and LMG3411R150 GaN with integrated driver and protection. The maximum power rating is 65W at 20V output but is adjustable for 20V/15V/9V/5V output voltage and 3A. This design reaches a peak efficiency of 93.7%. The average efficiency and standby power levels are designed to meet DoE level VI and CoC tier 2 limits. The compact design has dimensions of 2.54” x 1.13” x 0.95” (65mm x 28mm x 25mm).
