WLD3393 DEMO BOARD 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
configuration 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 fine 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.

CONFIGURING THE DEMO BOARD
STEP 2: CONFIGURE FOR CONSTANT CURRENT OR CONSTANT POWER MODE
The two modes of operation supported by the WLD3393 are constant current and constant power
mode. It is very important to note that the WLD3393 should be configured for either constant
current or constant power mode BEFORE power is applied. Changing operating mode while
the WLD3393 is operating can result in damage to your laser diode. In constant current mode,
VSet correlates directly to the laser diode current, regardless of laser diode power intensity. In constant
power mode, the WLD controls the laser diode using the photodiode to achieve a laser intensity that
is directly proportional to VSet.
Constant Current mode ignores the laser’s photodiode. The WLD3393, however, is designed to allow
you to monitor the laser’s photodiode while running in this mode. Monitor the voltage at the PDM pin on
the terminal block on the top side of the WLD3393. Before powering the unit on to operate in constant
current mode, make sure that the mode switch is in the CC position (see Figure 1). Select the output
current range by setting the LD RANGE jumper on the back of the WLD3393 to either the 200mA or
the 2A position. See Figure 4 for location.
Constant power mode utilizes the laser’s photodiode to regulate the intensity of the laser in proportion
to VSet. While the unit is NOT powered, make sure the mode switch is in the CP position to configure the
WLD3393 for constant power mode (see Figure 1). Set the PD RANGE jumper on the bottom of the
WLD3393 to either the 200μA or the 2mA range, depending on the specifications of your photodiode.
See Figure 6 for the location of the PD Current Range jumper. It is important to make sure that
the correct PD current range is selected as the WLD3393 may overdrive the laser if the PD range
is configured incorrectly, resulting in permanent damage to the laser. Use the LD RANGE jumper to
select between the 200mA and 2A range based on the rating of the laser load. See Figure 4 for the
location of this jumper.

STEP 3: INSTALL THE LASER DIODE CONFIGURATION BOARD
CAUTION: If the WLD3393 is configured incorrectly for the type of laser diode you are using,
damage can result to your laser diode and/or the WLD3393. Refer to Figure 5 to determine the
type of laser diode being used. To configure the WLD3393 for your laser diode type, connect the
configuration board to the bottom of the WLD3393 so that the arrow on the protruding edge of the
configuration board points to either A/B or C. Refer to Figure 6 for example installation.

STEP 4: ATTACH THE HEATSINK AND FAN (optional for less than +5V, 200mA operation)
HEATSINK REQUIREMENTS. The WLD3343 is designed to handle currents as high as 2.2A. The
WLD3393 demo board, however, limits output current to 2.0A. Attach a heatsink (such as WHS302
with thermal washer WTW002) to the WLD3343 when driving currents higher than 500mA. Attach a
fan (such as WXC303 (+5VDC) or WXC304 (+12VDC)) to the heatsink for output currents exceeding
1.0A. If using Wavelength accessories, refer to the WHS302, WTW002, WXC303, and / or the
WXC304 datasheets for assembly instructions.
FAN CONNECTIONS. Connect the fan leads to the (+) and (-) fan terminal positions on the terminal
block and secure with a small flat head screwdriver. The fan connects to the VDD supply, not VS, so care
must be exercised to ensure that the proper fan is selected, either +5VDC or +12VDC, when using
dual power supplies. Optionally, for lower noise operation, the fan leads may be connected directly to
a separate power supply compatible with the fan.
STEP 5: ATTACH THE VDD AND VSPOWER SUPPLIES
The WLD3393 has two power supply connections, VSand VDD. VSprovides power for driving the
laser (minimum current capacity greater than limit current setting). VDD provides power to the control
electronics (minimum 100mA). VDD can range from +5 to +12V. VScan range from +4.5 to +12V. For
simple operation tie VDD to VS. Use PGND for the power return. The common (COM) terminal on the
WLD3393 is not intended to act as a power connection, but as the low noise ground reference for
connecting an external VSET source, and for monitoring the IMON, PMON, and PDM signals.
A separate VSpower supply allows the output current stage to operate below the minimum 5V required
for the control electronics or up to the +12V maximum (for multiple laser diodes in series). Select VS
approximately 2.0 volts above the maximum voltage drop across the laser diode to reduce the power
dissipation in the WLD3343 component and minimize your heatsinking requirements. Note that for
type C laser diodes in Constant Power mode VDD must be greater than or equal to VS to keep the pho-
todiode signal in range.
NOISE REDUCTION. For better performance, to reduce noise in the control electronics, it is
recommended to connect VDD and VS together at the power supply, running separate wires for VDD and
VS. Grounding the heatspreader also can reduce noise. With WLD3393 Rev. B, the screw threads
contact a grounded PEM on the board; no ground strap is necessary.

WLD3393-00400-A Rev F
STEP 6: SET THE LASER DIODE CURRENT LIMIT
The WLD3393 LIM trimpot adjusts the laser diode current limit from zero to the full 200 mA or
2.0 Amps, depending on the laser diode current range selected. For accurate laser diode current limit
configuration follow these steps sequentially:
1. Connect the demo board’s LDA and LDC terminals directly to an ammeter capable of sensing
your maximum laser diode current. If you are using more than +5VDC power supply
voltage, place a resistor in series with the ammeter to reduce power dissipation across the
WLD. The following equations should be used.
Example calculation: VS= +12V, ILIM = 2A; RLOAD = (12-2.5)/2 = 4.75 ohm; 22*4.75= 19W
Another example: VS= +9V, ILIM = 0.5A; RLOAD = (9-2.5)/0.5 = 13 ohm; (0.5)2*13 = 3.25W
2. Configure the demo board for Constant Current (CC) mode operation. See Step 2.
3. Turn the SET trimpot fully counter clockwise (OFF). Adjust the LIM trimpot fully clockwise
(ON).
4. Apply power to the WLD3393 and enable the output current by switching the enable switch to
the “ON” position. See Figure 1 to locate the switch.
5. Turn the SET trimpot clockwise until the desired maximum current is achieved. Turn
the LIM trimpot counter clockwise until the current just begins to decrease. Turn the
SET trimpot back fully counterclockwise.
6. Disable the output current by switching the enable switch to the “OFF” position. Remove power
from the WLD3393.
STEP 7: CONNECT THE LASER DIODE AND MONITOR PHOTODIODE
With power removed from the WLD3393 board, connect the output (4 wire cable) to your laser diode
as indicated in Table 1. Firmly press the output cable into the output connector.

WLD3393-00400-A Rev F
STEP 8: MONITOR THE LASER DIODE AND PHOTODIODE CURRENTS
The input connector includes three signals for externally monitoring the WLD3343 laser driver output.
IMON, PMON, and PDM allow for monitoring of laser diode current and power intensity depending on
the selected mode of operation. The voltages at IMON, PMON, and PDM are all referenced to the
common terminal (COM) on the input connector.
IMON provides a mechanism for externally monitoring the laser diode current. IMON is available at all
times in both CC and CP modes. In the 200mA range, VIMON has a transfer function of 100mA/V. In the
2.0A range, VIMON has a transfer function of 1.0A/V. Table 3 summarizes this data.
PMON provides an external indication of the laser diode intensity by measuring photodiode current.
Since PD+ and PD- on the WLD3343 are shorted together in CC mode, PMON will only monitor
photodiode current in CP mode. When operated in the 200μA range, VPMON has a transfer function
of 100μA/V. When operated in the 2mA range, VPMON has a transfer function of 1mA/V. Table 4
summarizes this data.
PDM provides a mechanism for monitoring photodiode current in either CC or CP mode. While PMON
monitors the feedback used by the control electronics to maintain constant power of the laser, PDM
is an external monitor that is independent of the control electronics of the WLD3343. The transfer
function for VPDM to IPD is the same as for the PMON signal. PDM is only accessible on the terminal
block.

WLD3393-00400-A Rev F
STEP 10: ENABLE OR DISABLE THE OUTPUT CURRENT
The WLD3343 output current can be enabled and disabled using the onboard toggle switch. The
output is enabled when the green ON LED indicator is lit (see Figure 1).
CHARACTERIZE YOUR LASER DIODE. Configure the WLD3393 for Constant Current mode. Step
the external voltage setpoint to scan laser diode current. Monitor the intensity of the laser diode using
PDM.
STEP 9: ADJUST THE SETPOINT VOLTAGE
The setpoint controls the output of the WLD3343. In constant current mode the setpoint is directly
proportional to the laser diode current. In constant power mode the setpoint is directly proportional to
photodiode current, allowing for control of the power of the light emitted from the laser diode.
The setpoint voltage can be adjusted either by using the onboard SET trimpot, by applying an external
setpoint voltage, or by summing an external setpoint voltage with the setpoint dialed in using the SET
trimpot. The sum of the external setpoint voltage and the value dialed in using the SET trimpot can be
adjusted from 0 to 2.5 Volts.
To use only the onboard SET trimpot, place the VSET SOURCE jumper on the bottom of the WLD3393
evaluation board in the “T” position, and do not connect an external voltage source to the SET terminal
on the terminal block. The SET trimpot will allow the setpoint be be adjusted from 0V to 2.5V. Figure 6
shows the jumper location.
To use an external voltage source summed with the setpoint voltage from the on board SET trimpot,
place the VSET SOURCE jumper on the bottom of the WLD3393 to the “T” position. Connect an
external voltage source to the SET terminal on the terminal block on the top of the WLD3393 evaluation
board. The resulting setpoint voltage will be the sum of the voltage dialed in using the SET trimpot,
and the voltage applied to the SET terminal. Figure 6 shows the jumper location.
To use an external voltage source only for the setpoint, place the VSET SOURCE jumper on the bottom
of the WLD3393 board to the “X” position and connect the external setpoint voltage source to the
SET terminal on the terminal block on the top side of the WLD3393 evaluation board. When the SET
SOURCE jumper is in the “X” position, the voltage dialed in using the SET trimpot on the WLD3393 is
ignored. Figure 6 shows the jumper location.
In case an external voltage source is not availabe, but setpoint adjustment needs to be external,
a remotely located potentiometer can easily be connected to the WLD3393 to adjust the setpoint.
To used a remote potentiometer, connect the CW lead of the potentiometer to the terminal position
marked 2.5 on the terminal block on the top of the WLD3393 board. Connect the CCW lead of the
potentiometer to the COM terminal and connect the wiper to the SET terminal and ensure that the
VSET SOURCE jumper on the bottom of the board is set to the X position.
