Isolated 2.5-W SiC & IGBT gate-drive reference design with integrated switch PSR flyback converter

Design files

Overview

This reference design provides two isolated voltages from a 24-V DC input supply. By means of zero ohm resistors, it is possible to configure the two independent outputs as +15 V and +4 V, or +15 V and -4 V with common ground with a total power of 2.5 W. The integration of a 100-V rated primary-side switch, together with the elimination of an auxiliary winding in the transformer, enables a compact solution.

Features
  • High-voltage isolation
  • No optocoupler needed (PSR)
  • Configurable for single or multi-output applications
  • Several transformers available for different Vin / Vout range
