CIRCUIT PERFORMANCE
The EPC9115 demonstration circuit was designed to showcase the
size and performance that can readily be achieved using eGaN
FETs. The 300 kHz operating frequency is 50% - 100% higher than
typical commercial eighth-brick converters.
Figure 4 shows typical full-load waveforms for a 52 V input voltage
using probe tip adapters as shown in Figure 3. Figure 5 shows efficiency
plots for several input voltages at 400 LFM (2 m/s) airflow at 25 °C.
Data are taken after converter reaches thermal steady state.
