The WLD3343maintains precision laser diode current (Constant Currentmode) or stable photodiode current (Constant Power mode)regulation using electronics that are compatible with anylaser diode type. Safely supply up to 3 A of current (model-dependent) to a laser diode from a single +5 V power supply.MODEL VARIATIONSThere are five laser diode driver models available in theWLD family. The standard WLD3343 provides up to 2.2 A tothe laser diode. The WLD3343-3A provides up to 3 A. TheWLD3343-2L and WLD3343-3L are lower noise versionsfor Constant Current mode of the 2.2 and 3 A models,respectively. The WLD3343-HB is designed to operate withlower voltage supplies, including lithium-ion batteries.RAPID PROTOTYPINGUse the WLD3393 Evaluation Board to rapidly prototypea complete laser diode control system using the ofthe WLD3343 laser diode driver. Onboard switches,connectors, and trimpots make the configuration andoperation simple. Input and output cables are also includedwith the WLD3393.The WLD3343 is excellent for VCSELs, electro-opticalequipment, and medical/dental systems.ACCESSORIESIn addition to the WLD3393 Evaluation Board, there arethermal management kits designed specifically for theWLD. WEV300 includes a thermal washer and heatsink.WEV301 adds a +5 V fan, while WEV302 adds a +12 Vfan to the kit. Additionally, there are various power suppliesavailable that fit any current/voltage needs.FEATURES AND BENEFITS• Low cost• Slow-start laser diode protection• Drive up to 3 A output current• Constant Current or Constant Power operation• Compatible with any laser diode type• Small package size (1.3” × 1.26” × 0.3”)• Voltage-controlled setpoint• TTL-compatible shutdown pin• Adjustable current limit• Adjustable current range• 2 MHz Constant Current bandwidth• Over-temperature shutdown• 14-pin DIP PCB mountCONTENTSQUICK CONNECT GUIDE 2PIN DESCRIPTIONS 4ELECTRICAL SPECIFICATIONS 6SAFETY INFORMATION 8OPERATING INSTRUCTIONS — GENERAL 9OPERATING INSTRUCTIONS — STANDALONE 10OPERATING INSTRUCTIONS — WITH EVALUATION BOARD 16ADDITIONAL TECHNICAL INFORMATION 22TROUBLESHOOTING 25MECHANICAL SPECIFICATIONS 26CERTIFICATION AND WARRANTY 28ePAGEPbRoHSCompliant© September 2018ALaser TypeBLaser TypeCLaser Type406-587-4910www.teamWavelength.comWLD3343 & WLD3393Laser Diode Driver & Evaluation BoardDATASHEET AND OPERATING GUIDE
