Output 115 V / 0.08 A
Output 28 V / 0.08 A
IC revisionE1

Description

This reference design is a dual-output, isolated fly-buck power module for a single IGBT driver bias using the TPS54308 synchronous buck converter. The converter generates one non-isolated output of +3.3 V with 400-mA current capability and two isolated outputs of +15 V and -8 V with 80-mA current capability from an input voltage range of 9 V to 22 V.

Features

  • 1.25-kV isolation level mitigates noise between output and input
  • 1% accuracy on each 3.3-V output to meet high-precision specifications
  • Compact design with low profile transformer, which allows for easy integration into end system

Typical applications

  • IGBT driver
