High Efficiency, High Power Density Active Clamp Flyback Adapter with SJ FET Reference Design

Overview

TopologyFlyback Converter
Input voltage85-265 V
Output 19 V / 5 A
IC revisionE1

Description

PMP40328 is a maximum 9V 5A reference design for high frequency and high density adapter applications. The solution implements a high efficiency active clamp flyback controller UCC28780 and secondary rectifier controller UCC24612-2. The efficiency is around 90% at full load. Integrated input UVLO, and output OVP, OCP,SCP improve the power system reliability. The design is achieved in a compact form factor (52mm X 31mm X 31mm).

Features

  • Zero voltage switching over universal AC input
  • Synchronous rectifier using drain-to-source voltage sensing
  • Integrated input UVLO, output OVP, OCP, SCP
  • Compatible with USB PD PPS protocol from 6.2V5A to 9V5A
  • Size LWH 52mm31mm31mm

Typical applications

  • Adapter
