DESCRIPTION

This development board is in a monolithic half bridge topology with onboard gate drives, featuring
the EPC2106 eGaN (Enhancement-mode Gallium Nitride) Integrated Dual FET. The purpose of
these development boards is to simplify the evaluation process of these eGaN FETs by including all
the critical components on a single board that can be easily connected into any existing converter.
The development board is 2" x 1.5" and contains a dual integrated eGaN FET, in a half bridge
configuration using the Texas Instruments LM5113 gate driver, supply and bypass capacitors. The
board contains all critical components and layout for optimal switching performance. There are
also various probe points to facilitate simple waveform measurement and efficiency calculation. A
complete block diagram of the circuit is given in Figure 1.
For more information on the EPC2106 eGaN Integrated Dual FET, please refer to the datasheets
available from EPC at www.epc-co.com. The datasheet should be read in conjunction with this
quick start guide.

Demonstration Board Notification
EPC9055 boards are intended for product evaluation purposes only and are not intended for commercial use. As evaluation tools, they are not designed for compliance with the European Union directive on
electromagnetic compatibility or any other such directives or regulations. As board builds are at times subject to product availability, it is possible that boards may contain components or assembly materials
that are not RoHS compliant. Efficient Power Conversion Corporation (EPC) makes no guarantee that the purchased board is 100% RoHS compliant. No Licenses are implied or granted under any patent
right or other intellectual property whatsoever. EPC assumes no liability for applications assistance, customer product design, software performance, or infringement of patents or any other intellectual
