Efficient Power Conversion has expanded its product lineup with the introduction of the EPC91116, a laser driver evaluation board designed for indirect time-of-flight applications in automotive and industrial sensing environments. The board is built around the automotive-qualified EPC2203 gallium nitride power transistor, enabling nanosecond-scale performance with a straightforward architecture.
The EPC91116 addresses growing demand for time-of-flight systems in automotive driver monitoring, in-cabin sensing, and 3D mapping applications. It supports peak currents exceeding 10 A, pulse widths as narrow as 5 ns, and switching frequencies up to 100 MHz, making it appropriate for demanding sensing applications.
The board incorporates automotive-qualified components, including the compact EPC2203 GaN FET measuring 0.9 mm × 0.9 mm with specifications of 80 V, 17 A pulsed capability, 670 pC total gate charge, and 80 mΩ RDS(on). It also uses the AEC-Q100-qualified 74LVC2T45GS logic-level translator for enhanced reliability.
Engineers will find implementation simplified through the design’s approach to gate drive, which uses a CMOS logic IC rather than specialized gate drivers. The board handles input logic levels from 1.2 V to 5.5 V with minimal modification and includes a built-in Narrow Pulse Generator option for producing tunable pulse widths between 5 and 60 ns.
The EPC91116 comes with the EPC9989 interposer board for mounting various laser diodes and loads, making it suitable for automotive-grade time-of-flight designs and other fast-switching applications like Class-E amplifiers, SEPIC converters, and lidar systems. Technical documentation including datasheets and schematics is available on the EPC website.
