Overview

80-V 10A Power Stage EVM - The LMG1205 half-bridge EVM board is a small, easy to use, power stage with an external PWM signal. The EVM is suitable for evaluating the performance of the LMG1205 driving a GaN half-bridge in many different DC-DC converter topologies. It can be used to estimate the performance of the half-bridge to measure efficiency. The module is capable of delivering a maximum of 10A of current. However, adequate thermal management (forced air, running at low frequency etc) should be followed to ensure that the maximum operating temperature specification  for the on-board components is not exceeded. The EVM is not suitable for transient measurements as it’s an open loop board.

Features
  • Input voltage operates up to 80V
  • Simple open loop design to evaluate performance of LMG1205 driving a GaN Half-Bridge
  • VDD supply generated from an onboard linear regulator
  • Single PWM  input on board for PWM signal with < 8ns dead time
  • Kelvin sense capability for input and output to measure efficiency
  • Output current sense shunt resistor
Half-bridge drivers
LMG1205 1.2-A, 5-A 90-V, half bridge gate driver with 5-V UVLO for GaNFET and MOSFET
