Three-Phase AC and DC Input to 24V at 125mA Quick-Startup Isolated Flyback Reference Design

PMP10195

Design files

Overview

This design supplies an isolated 24V at 125mA from three-phase AC mains and DC input voltage. Since a maximum 70-ms startup time is necessary and the maximum input voltage is 1260 Vdc, a low-loss startup network has been developed. In order to reduce the stress on the FET, a cascode configuration has been selected. The controller features constant switching frequency and low quiescent current. A small form factor makes it suitable for electronic breaker supply.

Features
  • LM5020-based isolated flyback in constant switching frequency delivering 24V at 125mA
  • 80% peak efficiency at full load and 325Vdc input voltage
  • Extremely wide input voltage range: 56Vac to 891Vac
  • Less than 70-ms startup time
  • Magnetic feedback: no optocoupler is needed
