Overview

This isolated primary-side regulated (PSR) flyback converter reference design provides dual +15-V outputs at 100 mA each. It was designed to provide bias power for a rotor coil excitation gate driver in motor/ inverter applications. The isolated output voltage is sampled from the primary-side flyback voltage eliminating the need for an optocoupler, voltage reference or third winding from the transformer for output voltage regulation. It offers a high level of integration and high efficiency in a compact form factor.

Features
  • Primary-side regulation eliminates optocoupler or transformer bias winding which results is a compact size
  • Excellent balanced load output voltage regulation (<1% from 10% - 100% loading)
  • Excellent unbalanced load output voltage regulation (<1% @ 50%, <2% @ 90% imbalance)
  • High efficiency (>90% from 50% - 100% loading)
  • LM5180 controller integrates FET and minimizes external components
