Output Current LD 200-400 mA; DIP PCB Mount; Compatible with Type A, B & C Lasers 

Wavelength Electronics’ LDD P series of laser diode drivers come in two compact models to work with all laser diode/photodiode configurations. While the LDDX00-1P version drives type A & B laser diodes, the LDDX00-2P variant drives type C laser diodes. Each model is available in 200 mA and 400 mA versions to best fit your laser diode requirements.

Very low leakage current (15 µA) makes the LDD P series ideal for driving most VCSELs using the remote modulation setpoint input. It operates from 5 to 12 V. Just add an external power supply and your laser diode to this simple 8-pin controller.

When it is essential to have high performance in your application, these low-noise drivers offer excellent current stability in constant current mode. Precisely control the laser diode setpoint current with the onboard output current adjust trimpot or via a remote voltage to the modulation input. The modulation input’s small signal 3 dB bandwidth is DC to 2 MHz.

For easy integration, the LDD P series allows users to measure laser diode current from a buffered monitor output. Optional evaluation boards are available to assist with operating any LDD P series module. An evaluation board and cable are available to speed implementation of the LDD laser diode driver in your application.

In order to protect laser diodes, all LDD P series drivers are equipped with current limit protection, as well as slow start circuitry. Current limit protection ensures that the diode will not be overdriven, and the slow start circuitry protects the diode from thermal shock that can damage the laser at turn on. Adjust the limit current trimpot to protect the laser diode from exceeding its maximum current rating even when modulating your laser diode.

Free, effective and responsive technical support is available to simplify integration of Wavelength products into your OEM design. Standard product can be easily modified to meet your application requirements. Get in touch with the AMS Technologies laser diode driver experts to discuss your customized solution!
