EPC9181: 80 V, 125 A pulsed laser diode driver evaluation board
The EPC9181 evaluation board is primarily intended to drive laser diodes with high current pulses with pulse widths in the single digit nanosecond range. The board uses the fully automotive qualified EPC2204A.
The board ships with the EPC9989 interposer board to provide the user with a simple means of mounting a small set of commercially available lasers. The EPC9989 has a collection of breakaway 5 mm square interposer PCBs with footprints for different lasers and various alternative loads. The use of the interposers allows many different lasers or other loads to be mounted on the evaluation boards. The boards do not include a laser diode or load, which must be supplied by the user.
