Description

The PMP10129 has been designed especially for E-meters. It uses the LM5021 flyback controller to provide two isolated outputs (6V and 24V) from an 3-phase input. The input voltage range is between 90VAC and 460VAC.

Features
  • Isolated Flyback Topology
  • 3-Phase Input
  • Constant Switching Frequency
  • This reference design was built and tested and the test report is included
