PCO-7114-22-2 Laser Diode Driver Module
Precision Pulse Control
The PCO-7114-22-2 is a compact and economical pulsedcurrent OEM laser diode driver module with current range from 6 A to 22 A with a fixed pulse width of ≤ 2 ns typical. It is designed to provide extremely fast current pulses for driving laser diodes in range finder, LIDAR (Light Imaging, Detection and Ranging), ADAS (Advanced Driver Assistance Systems), atmospheric communications and other applications requiring high-current nanosecond pulses.
Laser Diode Connection
Mounting pads are provided to mount the laser diode directly to the driver. The four-hole mounting pattern accepts TO-18, TO-5, TO-52, 5.6 mm, and 9 mm packages. To facilitate various packages and mounting preferences, two solder pads at the end of the board accept various laser diode packages mounted on-axis to the driver. Alternately, low-inductance stripline cable can be used for connection to a remotely-located diode.
System Operation
Output current is controlled with the voltage at the high- voltage input. The output frequency is the same as the pulses fed to the trigger input. A current monitor output is provided to observe the laser diode current in real time with an oscilloscope.
