DESCRIPTION
These development boards are in a monolithic half- bridge topology with on-board gate drives,
featuring the EPC2100/1/5 eGaNICs (Enhancement-mode Gallium Nitride Integrated Circuit).
The purpose of these development boards is to simplify the evaluation process of these
monolithically integrated 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 2" and contains one eGaNIC in 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 and has additional area to add buck
output filter components on board. There are also various probe points to facilitate simple wave-
form measurement and efficiency calculation. A complete block diagram of the circuit is given in
Figure 1.
For more information on the EPC2100/1/5 eGaNICs, 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.

**Maximum input voltage depends on inductive loading, Maximum switch node ringing must be kept under device rated voltage.
* Maximum current depends on die temperature – actual maximum current with be subject to switching frequency, bus voltage and thermal cooling. eGaNIC
intended for high step-down ratio applications.

Demonstration Board Notification
These 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
property rights of any kind.
