PMP4478

AC in, 5V 3A Quasi-resonant Flyback Converter with Optimized Light Load Efficiency Reference Design

PMP4478

Design files

Overview

The PMP4478 is an optimized reference design for appliance applications which provides high current.  Low ripple & noise < 50mV is achieved via Pi type filter at the output. The design also achieves good light load efficiency with optimized transformer design. When the load is 300mW, the input power can still be limited to less than 420mW.

Features
  • Optimized design for high light load efficiency (Input power <420mW when load is 300mW)
  • Low Standby Power(<30mW)
  • Low ripple& noise (<50mV)
  • Good Dynamic performance
  • Pass CE/RE Test
  • Full Input & Output Protection
