THERMAL CONSIDERATIONS
The EPC9085 development board showcases the EPC2049 eGaN
FET. The EPC9085 is intended for bench evaluation with low ambient
temperature and convection cooling. The addition of heat-sinking and
forced air cooling can significantly increase the current rating of these
devices, but care must be taken to not exceed the absolute maximum
die temperature of 150°C.
NOTE . The EPC9085 development board does not have any current or thermal
protection on board.
For more information regarding the thermal performance of EPC eGaN FETs, please
consult:
D. Reusch and J. Glaser, DC-DC Converter Handbook , a supplement to GaN Transistors for
Efficient Power Conversion , First Edition, Power Conversion Publications, 2015.
