• Constant Power Supply
• APC Laser Driver, 0 – 250 mA
• Supports Laser Diodes with Pin Style A, B, D, and F

The LD1100 Laser Diode Driver is a constant-power laser driver module that supports common laser anode and common laser cathode pin configurations. It features an on-board 12-turn trim pot for continuous laser power output adjustment, pin-programmable feedback gain, ON/OFF control input, and a current monitor output for observing the laser drive current. The compliance voltage, which is the maximum output voltage, is ~6.5 V when using a 12 V power supply. This driver can drive lasers up to 250 mA in a constant-power mode and uses the internal monitor photodiode for a feedback signal into a proportional-integral feedback loop to stabilize the output power to within 1.5%. All input and output signals are provided on a 12-pin SIP connector, which allows simple integration into a printed circuit design.
