Typical Performance Curves
This evaluation board is intended to demonstrate GaN FET technology and is for demonstration
purposes only and no guarantees are made for standards compliance.
There are areas of this evaluation board that have exposed access to hazardous high voltage
levels. Exercise caution to avoid contact with those voltages. Also note that the evaluation
board may retain high voltage temporarily after input power has been removed. Exercise
caution when handling.
When testing converters on an evaluation board, ensure adequate cooling. Apply cooling air
with a fan blowing across the converter or across a heatsink attached to the converter. Monitor
the converter temperature to ensure it does not exceed the maximum rated per the datasheet
specification.
