programmed to speci c values to determine the impact of load
resistance on the performance of the system.
Both the source and device boards come equipped with various
probe points to facilitate simple waveform measurement and ef-
ciency calculations. A complete block diagram of the system is
given in Figure 1.
For more information on the EPC2014 eGaN FET please refer to
the datasheet available from EPC at www.epc-co.com. The data-
sheet should be read in conjunction with this quick start guide.
