ToF demo board drives lasers with currents up to 28A

January 26, 2020  Stephen Law

EPC9144 15V, 28 high current pulsed laser diode driver demonstration board is suitable for use in time-of-flight systems, where speed and accuracy of object detection is critical. Board demonstrates the rapid transition capability of the AEC Q101-qualified EPC2216 provides power pulses to drive laser diodes, VCSELs or LEDs up to ten times faster than an equivalent MOSFET, in a small fraction of the area, energy, and cost. eGaN FETs and integrated circuits provide the high current pulses, extremely narrow pulse widths, and small size that make affordable, high performance lidar possible. The short pulse width lead to higher resolution, and the tiny size and low cost make eGaN FETs ideal for time-of-flight applications from automotive to industrial, healthcare to smart advertising, gaming, and security. Demo board ships with an interposer board. The interposer board is a collection of break-away 5 mm x 5 mm square interposer pcbs with footprints to accommodate different lasers, RF connectors, and a collection of other footprints designed for experimentation with different loads.
