说明
- PMP4372, demonstrates a low cost single PCB board solution for 5V1.5A adapter. By using primary side regulation (PSR) mode chip UCC28720 which drives bipolar power device, average efficiency > 80% @230Vac is achieved. Output ripple < 80mV, and Vo(min) > 4.32V with 0 to 0.5A load transient. The overall size is limited in 43mm(L)X28mm(W)x16mm(H) and no load power is less than 20mW
