Development Board EPC9150 Quick Start Guide:EPC2034C 200 V High Current Pulsed Laser Diode Driver

PublishTime：2022-05-24

●The EPC9150 demonstration board is primarily intended to drive laser diodes with high current pulses with total pulse widths of < 3 ns possible (half amplitude full width).The board is shipped with a EPC2034C enhancement mode (eGaN®) field effect transistor (FET).The EPC2034C is a 200 V FET capable of current pulses up to 214 A.The EPC9150 ships with the EPC9989 interposer board.The EPC9989 has a collection of break-away 5 mm square interposer PCBs with footprints for different lasers and a collection of other footprints.The use of the interposers allows many different lasers or other loads to be mounted while still being able to use the EPC9150.The boards do not include a laser diode or load, which must be supplied by the user.
●The power stage of the EPC9150 comprises a ground-referenced 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 discharge capacitor current,and is equipped with high bandwidth SMA connectors for input and sensing.In addition,the board includes a narrow pulse generator capable of sub-nanosecond precision,or the user can simply send the input to the gate drive directly.As shipped,the board is dsigned 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 applications 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 Figures 7,8,and 9.
●The datasheet should be read in conjunction with this quick start guide.In addition,EPC provides an application note: AN027 eGaN FETs for Lidar – Getting the Most Out of the EPC9126 Laser Driver. While the note discusses Rev. 2 of the EPC9126,most of the methods and analysis are applicable to the EPC9150.
