Texas Instruments UCC28720 | Demoboard PMP4372 | Würth Elektronik Reference Design Search

Overview

Topology	Flyback Converter
Input voltage	85-264 V
Output 1	5 V / 1.5 A
IC revision	A

Description

This reference design demostrates 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 0~0.5A load transient. The overall size is limited in 43mm(L)X28mm(W)x16mm(H) and no load power is less than 20mW.
