EPC9144 Development Board Quick Start Guide
The EPC9144 development board is primarily intended to drive laserdiodes with high current pulses with total pulse widths as short as 1.2 ns and currents of up to 28 A. The board is designed around the EPC2216enhancement mode (eGaN®) field effect transistor (FET). The EPC2216 is an AEC-Q101 automotive qualified 15 V FET capable of current pulses up to 28 A. The EPC9144 ships with the EPC9989 interposer board. The EPC9989 is a collection of break-away 5 mm 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 while still being able to use the EPC9144. Laser diodes or other loads are not included, and must be supplied by the user.
The EPC9144 comprises a ground-referenced EPC2216 eGaN FET driven by a Texas Instruments LMG1020 gate driver. 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 con-nections for input and sensing. In addition, the board includes a narrow pulse generator capable of sub-nanosecond operation, or the user can simply feed the gate drive directly via removal of a resistor. As shipped, the board is designed to operate from 3.3 V logic, but is equipped with both a logic level translator and a differential receiver to accommodate different use cases. Finally, the board can also be used for other applica-tions requiring a ground-referenced eGaN FET, e.g. Class E amplifiers or similar. A complete block diagram of the circuit is given in figure 1, and a detailed schematic in figure 4.
