WLD3343 - Ultrastable Driver for Laser Diodes


The WLD3343 is an easy-to-use analog circuit for space contstrained
, high-power laser diode applications. The WLD3343 maintains precision
laser diode current (constant current mode) or stable photodiode
current (constant power mode) regulation using electronics that are
compatible with any laser diode type. Safely supply up to 2.2 Amps
of current to your laser diode from a single +5 Volt power supply.
