Technical detail about product Datasheet
The WLD3343HB is a general purpose laser diode driver that maintains precision laser diode current (Constant Current mode) or stable photodiode current (Constant Power mode) using electronics that are compatible with any laser diode type. It delays and slowly ramps the current for maximum protection. Supply up to 2.2 A of current to your laser diode from a single supply (+3.3 V to +6 V). The WLD3343HB is compatible with Lithium-Ion batteries. For higher compliance voltage, the WLD3343 operates from +5 V to +12 V.

An internal thermostat shuts down the WLD safely if the device temperature exceeds 105°C. Remotely enable or disable current. Zero leakage current makes it perfect for VCSELs. Current range is scaled by an external resistor.

For 3 A operation, the WLD3343-3A is available. To drive with lower noise in Constant Current Mode only, the WLD3343-2L and WLD3343-3L drive up to 2 A and 3 A respectively. A circuit calculator tool speeds selection of external component values (see Design Tools tab). An evaluation board is available to simplify prototyping: WLD3393. Heatsinking solutions to use the WLD3343HB at full current are available.

This laser diode driver is ideal for applications where space is tight. It is widely used in electro-optic qualification, raman spectroscopy, medical diagnostic equipment, range finders, and on research benches.

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.
