WLD3343 Laser Diode Driver
Description
The WLD3343 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 +5 V power source.
An internal thermostat shuts down the WLD safely if the device temperature exceeds 105°C. Remotely enable or disable current. Zero leakage current allows operation with VCSELs. Current range is scaled by an external resistor.

Features
To operate from 3.6 V (for Lithium-Ion batteries) try the WLD3343HB. 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 WLD3343 at full current are available.
Applications
This laser diode driver is ideal for applications where space is tight. It is widely used in electro-optic instrumentation, spectrometers, medical diagnostic equipment, range finders, and on research benches.
