EPC9101: 1.2V @ 18A, 9 ~ 18V in

Summary

The EPC9101 demonstration board is a 1.2 V output, 1 MHz buck converter with an 18 A maximum output current and 8 V to 19 V input voltage range. The demonstration board features the EPC2014 and EPC2015 enhancement mode field effect transistors (eGaN® FETs), as well as the first eGaN FET specific integrated circuit gate driver – the Texas Instruments LM5113. The LTC3833 from Linear Tech controls the circuit.

The EPC9101 board is intended to showcase the performance that can be achieved using the eGaN FETs and eGaN gate driver together.

The EPC9101 demonstration board is 3” square and contains a fully closed loop buck converter.
