PCO-7115-5-1 Laser Diode Driver Module
Precision Pulse Control
The PCO-7115-5-1 is a compact and economical pulsedcurrent OEM laser diode driver module with a current range of 0.5 A to 5 A with a fixed pulse width of 1 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.

Notes
Warranty: One year parts and labor on defects in materials and workmanship.
All specifications were measured in a free-air environment with an ambient temperature of 25°C. Since resistors R1 and R2 create an unwanted worst-case heat source of about 3.7 W, we recommend air cooling the PC board with a minimum 17.66 CFM airflow source. The exhaust air should ideally be located behind R1 and R2 such that the hot airflow exits directly and does not traverse across the module. This additional cooling is especially recommended when operating above 3 A with a frequency of greater than 600 kHz and/or if this module is operated in a confined area where heat is likely to build up. In general, the user should allow a 15 minute warm-up period to obtain a more stable output. Stability can be greatly improved by adding an airflow cooling source as described above.
All electrical measurements were taken via the current monitor connection while driving a shorted load.
Specifications are subject to change without notice.
