Texas Instruments UCC25800-Q1 | Demoboard PMP23216

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

Overview

TopologyLLC Resonant Converter
Input voltage12 V
Output 112 V / 0.1 A
IC revisionA

Description

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

Typical applications

  • Power Supply
  • Automotive and Transportation
  • Alternative Energy
  • Industrial and Automation
  • Energy Storage and Battery Management
