EPC9144 – 15 V High Current Pulsed Laser Diode Driver

EPC9144: 15 V high current pulsed laser diode driver demo board for Time of Flight (TOF)

EPC9144 LiDAR Demo Boards

The EPC9144 development board is primarily intended to drive laser diodes with high current pulses with total pulse widths as short as 1.2 ns and currents of up to 28 A.

The board is designed around the AEC-Q101 automotive qualified 15 V EPC2216 eGaN® FET.

The EPC9144 ships with the EPC9989 interposer board with footprints for different lasers, RF connectors, and a collection of other footprints designed for experimentation with different loads.

The use of the interposers allows many different lasers or other loads to be mounted while still being able to use the EPC9144. Laser diodes or other loads are not included and must be supplied by the user.
