Topology | Flyback Converter |
Input voltage | 85-265 V |
Output 1 | 20 V / 3.25 A |
IC revision | C |
This reference design is a low-cost, high-density USB adapter that uses the UCC28782 active-clamp flyback controller and UCC5304 isolated driver in a ZVS-flyback topology. The maximum power rating is 65 W at 20-V output but is adjustable for 20-V/15-V/9-V/5-V output voltages and 3 A. This design reaches a peak efficiency of 93.4%. 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 44 mm by 54 mm by 20mm (48cc open frame).
