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 L*W*H 52mm*31mm*31mm
