EPC9107: 3.3V @ 15A, 9 ~ 28V in

Summary

The EPC9107 demonstration board is a 3.3 V output, 1 MHz buck converter with an 15 A maximum output current and 9 V to 28 V input voltage range. The demonstration board features the EPC2015 enhancement mode (eGaN®) field effect transistor (FET), as well as the Texas Instruments LM5113 gate driver. (now replaced by the LMG1205)

The EPC9107 board contains the complete power stage (including eGaN / GaN FETs, driver, inductor and input/output caps) in a compact ½” x ½” layout to showcase the performance that can be achieved using the eGaN FETs and eGaN driver together.

The EPC9107 demonstration board is 3” square and contains a fully closed loop buck converter with optimized control loop.

There are also various probe points to facilitate simple waveform measurement and efficiency calculation.
