EPC9172 Development Board Quick Start Guide
■The EPC9172 development board is primarily intended to drive laser diodes with short, high current pulses. Capabilities include minimum pulse widths of < 2.5 ns, peak currents > 15 A, and bus voltage rating of 60 V. The board is shipped with an EPC21701 eToF™ Laser Driver IC. The EPC21701 monolithically integrates an ultrafast eGaN gate driver with and a 15 A, 80 V eGaN FET in one tiny 6-terminal LGA IC. The EPC9172 ships with the EPC9989 interposer board. The EPC9989 is a collection of break- away 5 x 5 mm square interposer PCBs with footprints for different lasers, RF connectors, and a collection of other footprints designed for experimentation with different loads. The use of the interposers allows many different lasers or other loads to be mounted on the EPC9172. Laser diodes or other loads are not included, and must be supplied by the user.
■The EPC9172 combines the EPC21701 eGaN IC with a printed circuit board with inputs, outputs, and test points in order to evaluate and demonstrate the capabilities of the IC and connected load. The printed circuit board is designed to minimize the power loop inductance while maintaining mounting flexibility for the laser diode or other load. It includes multiple on-board passive probes for voltages and is equipped with MMCX connections for input and sensing. The EPC21701 IC requires a 5 VDD supply, but is designed to interface with 3.3 V and 5 V CMOS logic families. In many cases it can also be driven from 2.5 V logic families. Finally, the board can also be used for other applications requiring a ground-referenced eGaN IC, e.g. Class E amplifiers, boost converters, or similar.
