Adjustable current laser diode driver

Laser Diode Current Source: One key section of a laser diode driver is the Adjustable Current Source. It can also be known as the Output Stage. It can also be known as the Output Stage. This section responds to the Control System section by driving current to the laser diode.

Laser diodes are harmful and should have some sort of constant current circuit as a basic protection for the laser diode. As result, I built this circuit which provides highly accurate current control. The module is a great tool to drive low-cost laser diodes with superb accuracy. This circuit can drive diode starting from 0 mA to mA, usually, these cheap diodes require around 30mA current. The project has an onboard multi-turn potentiometer to adjust the output current with great accuracy. A laser diode driver, sometimes also called laser diode power supply, is an adjustable current source that delivers exactly the current level to the laser diode that is needed for its best performance in a particular application. High power current source for driving Laser Diodes and Light Emitting Diodes. Current Range of Amps. Current Ranges are adjustable in ma increments. Integrated cooling fan; Soft start for diode protection. Reverse diode and ESD protection. Thermal Protection and Over Current Protection. Federal Compliant Safety Features.

Single +5V or V Power Supply; mA Supply Current; Operates to Gbps; 50Ω On-Chip Input Termination Resistors; Programmable Modulation Current to. Now just hook up your laser diode to the load terminal of the circuit and you should be able to control the current flow by adjusting the k potentiometer. The PCO provides the high speed, high current performance of our PCO product line and adds continuously adjustable pulse width providing.
