EPC9102: 12V @ 8 ~ 17A, 48V in

Summary

The EPC9102 demonstration board is a 12 V output, 375 kHz phase shifted full bridge (PSFB) eighth brick converter with 17 A maximum output current and 36 V to 60 V input voltage range. The demonstration board features the EPC2001 enhancement mode (eGaN®) field effect transistors (FETs), as well as the first eGaN FET specific integrated circuit driver – the National LM5113 from Texas Instruments. The EPC9102 board is intended to showcase the performance that can be achieved using the eGaN FETs and eGaN driver together.

The EPC9102 demonstration board is oversized to allow connections for bench evaluation.

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 EPC2001 eGaN FETs or LM5113 driver, please refer to the datasheets. These datasheets, as well that of the LM5030 controller should be read in conjunction with this quick start guide. GaN
