Half-bridge point-of-load converter reference design with GaN technology

Overview

TopologyHalf-Bridge Converter symmetrical isolated
Input voltage24-32 V
Output 11 V / 40 A
IC revisionB

Description

The board is a redesign of the LMG5200POLEVM-10 EVM. It modifies the inboard transformer turns ratio from 5:1 to 3:1 to reduce input the range. The original EVM was designed to evaluate the LMG5200 GaN half-bridge power stage and the TPS53632G half-bridge point-of-load (PoL) controller. This board implements the converter as a single-stage hard-switched half-bridge with a current-doubler rectifier. The board supports input voltages from 24 V to 32 V and output voltages between 0.5 V to 1.0 V with continuous output currents up to 40 A. This topology efficiently supports the high step-down ratio while providing significant output current and controllability.

Features

  • Low-voltage, high-current capability supporting FPGA PoLs
  • High power density using GaN FETs
  • Integrated planar transformer

Typical applications

  • Flight control system
  • Aircraft electrical power
