EPC91116 Demonstration Board

The EPC91116 from EPC is a demonstration board suitable for driving laser diodes with short-current pulses, achieving minimum pulse widths as low as 5 ns. It supports peak currents of more than 10 A and a bus voltage of 40 V. This high-speed performance is enabled by their gallium nitride enhancement-mode (eGaN®) FET technology. The board utilizes the fully automotive-qualified EPC2203, an ultrafast GaN transistor with a very low total gate charge (Q_G) of 670 pC. The GaN transistor has a rated pulse current of 17 A, a rated voltage of 80 V, and a very low R_DS(ON) of 80 mΩ while maintaining an exceptionally small footprint of 0.9 mm x 0.9 mm.
