PMP10055

Wide Input Range (140Vac to 440Vac) Non Isolated Off-line Flyback Converter with Multiple Outputs

PMP10055

Design files

Overview

An energy metering device very often needs non-isolated power, since the neutral is connected to the ground of the output. This is a typical application, when 1.8V, 3.3V, 12V and 18V are needed to supply digital and analog loads. Even though a small transformer is employed, the PSU delivers 9Wpeak power.

Features
  • Wide input voltage range (line-neutral and line-line)
  • Covers single phase and three phase applications
  • Small EP7 transformer
  • Uses high electrolytic capacitance value for 500msec hold-up time
