DESCRIPTION
The development board is in a half bridge topology with onboard
gate drives, featuring the EPC8000 family of high frequency en-
hancement mode (eGaN®) field effect transistors (FETs). The pur-
pose of these development boards is to simplify the evaluation
process of the EPC8000 family of 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 two eGaN FETs 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 mea-
surement and efficiency calculation. A complete block diagram of
the circuit is given in Figure 1.
For more information on the EPC8000 family of eGaN FETs, 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.
