EPC announces the availability of the EPC9144, a 15 V, 28 A high current pulsed laser diode driver demonstration board.
In time-of-flight systems, speed and accuracy of object detection is critical. As demonstrated on this board, 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 (more info).
