Topology | Flyback Converter |
Input voltage | 85-265 V |
Output 1 | 5 V / 1.2 A |
IC revision | A |
This reference design demostrates a low cost single PCB board solution for 5V1.2A cube charger. By using primary side regulation (PSR) mode chip UCC28720 which drives bipolar power device, average efficiency 78% @230Vac is achieved. The overall size is limited in 22mm(L)X21mm(W)x20mm(H) and no load power is 10mW typically.
