0 `描述及特性 This reference design demostrates a low cost single PCB board solution for 5V1A adapter. By using primary side regulation (PSR) mode chip UCC28720 which drives bipolar power device, average efficiency is 76%@115V and 77%@230Vac. PMP4373 achieves high precise CC and CV regulation with 0.15V cable compensation The overall size is limited in 35.7mm(L)* 25.7mm(W)14mm(H) and no load power is less than 10mW. The design is done with single PCB layer.
