The WLD3343 is a general-purpose analog hybrid circuit
for use in ultrastable laser diode driver 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. Supply up to 2 Amps of current to
your laser diode from a single +5 Volt power supply.
Connect two or more WLD3343 units together to
drive higher output currents.
