EPC launches three laser driver boards showcasing AEC-Q101 qualified GaN FETs' rapid transition for superior LiDAR system performance.

EL SEGUNDO, Calif.— December 2023 — EPC introduces three evaluation boards - EPC9179, EPC9181, and EPC9180 - featuring pulse current laser drivers of  75 A, 125 A, and 231 A , showcasing EPC’s AEC-Q101 GaN FETs. These FETs; EPC2252, EPC2204A, and EPC2218A are 30% smaller and more cost-effective than their predecessors. Designed for both long and short-range automotive lidar systems, these boards expedite solution evaluation with varied input and output options.

As the level of automation increases in machines, detailed awareness of the surroundings becomes necessary. Time-of-flight based 3D imaging systems have become the eyes of machines. eGaN^® technology has been the workhorse of laser drivers for these systems, enabling the resolution to make intelligent decisions.

It’s getting harder to avoid using GaN power transistors and ICs, says Alex Lidow. There are many reasons to use GaN-on-Si power transistors such as eGaN FETs, in telecoms, vehicles, healthcare and computing. Smaller, faster, lower cost, and more integrated, GaN-on-Si devices have spent a decade gaining the confidence and trust of designers across the spectrum of power conversion applications.

EPC will exhibit live demonstrations showing how GaN technology’s superior performance is transforming power delivery for entire industries including computing, communications, and automotive.

EL SEGUNDO, Calif. — March 2019 — The EPC team will be delivering eleven technical presentations on gallium nitride (GaN) technology and applications at APEC 2019 in Anaheim, California from March 17^th through the 21^st. In addition, the company will demonstrate its latest eGaN FETs and ICs in customers’ end products that are enabled by eGaN technology.

The reason eGaN FETs (and now ICs) are used in all the LiDAR systems for autonomous cars, and now autonomous race cars, is that they enable much higher resolution (due to extremely short laser pulses), faster image speed (due to short laser pulses), and the ability to see greater distances with high accuracy (due to fast laser pulses at very high current).

LIDAR is presently a subject of great interest, primarily due to its widespread adoption in autonomous navigation systems for vehicles, robots, drones, and other mobile machines. eGaN devices are one of the main factors in making affordable, high performance LIDAR possible in a small form factor thus further fueling the LIDAR revolution.

LIDAR is made up of a laser (or arrays) capable of transmitting pulsed light over the required range of interest, and a high-speed, low-noise receiver for reflected signal analysis. A portion of this light is reflected or scattered back to the receiver according to the reflectivity of the target.
