GENERAL DESCRIPTION:

Use the WLD3393 Evaluation Board to rapidly 
prototype a complete laser diode control system 
using the cutting edge technology of the 
WLD3343 Laser Diode Driver.  Onboard 
switches, connectors, and trimpots make 
con

fi

 guration and operation simple.  Input and 

output cables are also included.  

Operate in either constant current (CC) or 
constant power (CP) mode.  An onboard 
12-turn trimpot allows 

fi

 ne adjustment of laser 

diode forward current (CC Mode) or monitor 
photodiode current (CP Mode).  Another trimpot 
sets the laser diode forward current limit.  The 
input cable allows easy connection to your 
power supply and monitoring equipment while 
the output cable quickly connects to your laser 
diode and monitor photodiode.

High power applications can use the onboard 
fan connector to power a WXC303 or WXC304 
(+5 

VDC or +12 

VDC) fan attached to a 

WHS302 heatsink.
