EPC's EPC9126 and EPC9126HC development boards are primarily intended to drive laser diodes with high current pulses with total pulse widths as low as 5 ns (10% of peak).

The EPC9126 board is shipped with an EPC2016C enhancement mode (eGaN^®) field effect transistor (FET), a 100 V maximum device voltage capable of current pulses up to 75 A.

The EPC9126HC board is shipped with an EPC2001C eGaN FET, a 100 V maximum device voltage capable of current pulses up to 150 A.

The EPC9126xx comprises a ground-referenced eGaN FET driven by a Texas Instrument's LMG1020 gate driver. The boards also ship with an interposer board which provides multiple options for mounting laser diodes. The boards do not include a laser diode; this must be supplied by the user.
