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.
