WLD3393 DEMO BO
ARD FOR
THE
WLD3343
WLD3393-00400-A Rev F
GENERAL DESCRIPTION:
Use the WLD3393 Demo 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
confi 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.
