March 2021 — Efficient Power Conversion  (EPC) announces the availability of the EPC9150, a 200V, high current, pulsed-laser diode driver demonstration board. In a lidar system, used to create 3-D maps for autonomous vehicle applications, speed and accuracy of object detection is critical. As demonstrated by this board, the rapid transition capability of the EPC2034C eGaN FETs provide power pulses to drive the laser diodes, VCSELs or LEDs up to ten times faster than an equivalent MOSFET and in a small fraction of the area, energy, and cost. Thus, enhancing the overall performance, including accuracy, precision, and processing speed as well as the price of a lidar system.


eGaN® FETs and integrated circuits provide the high current pulses, extremely narrow pulse widths, and small size that make affordable, high performance lidar possible. Using the 200V, 12 square mm, EPC2034C eGaN FET, the EPC9150 can generate a 220A laser pulse peak in a pulse width that is only 2.9 nanoseconds wide. The high current increases the range of the lidar system, while the short pulse width leads to higher resolution, and the tiny size and low cost make eGaN FETs and ICs ideal for lidar applications from automotive to industrial robotics and security.


The EPC9150 ships with an interposer board. The interposer board is a collection of break-away 5mm×5mm square interposer PCBs with footprints to accommodate 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, allowing users to test the performance with the load requirements that are appropriate to their application.
