PMP23216

Highly-integrated, dual-output isolated bias supply reference design with reinforced insulation

PMP23216

Design files

Overview

This reference design generates two isolated +12-V rails at 100 mA each from a 12-VDC input voltage. The design is for a small footprint by using a primary resonant LLC topology with a single driver and transformer with reinforced insulation. This design can be used for an application where bias power is needed across a high-voltage isolation barrier.

Features
  • Small size with simplified LLC design
  • High efficiency of 85% at full load
  • Dual output for high-side and low-side drivers
  • Uses small and low-cost transformer
  • Reinforced insulation for bias supplies crossing high-voltage isolation barriers
