PLD SERIES LASER DIODE DRIVER
TROUBLESHOOTING
PROBLEM
POTENTIAL CAUSES
SOLUTIONS
Driver will not switch on
Improperly configured power
supply
Carefully check the wiring diagram according to
Table 3.
Output will not enable
Remote Enable signal is not
correct
Refer to the LD Enable specifications in
Table 1 and make sure your
input enable signal is correct.
Laser output power too
low in Constant Current
mode
Laser current setpoint too low
Increase the setpoint either by adjusting the I SET trimpot clockwise,
or by increasing the signal voltage on the Analog Input (pin 9).
Laser current limit too low
Refer to
page 12 for instructions on setting the laser driver current
limit.
Laser driver is compliance
limited
Check the laser diode specifications to determine the forward
voltage (V
F). Make sure that the PLD is not compliance limited. Refer
to the Electrical Specifications table on
page 6. If the driver is
compliance limited, V
LD ANODE may need to be increased. Verify that
the PLD will be operating within the Safe Operating Area if
V
LD ANODE is increased.
Laser does not reach
desired output in
Constant Power mode
Current limit too low
Check the laser diode datasheet to determine the approximate laser
drive current at the desired optical power output level. Then verify
that the current limit is set slightly higher than that. See
page 12 for
instructions on setting the laser driver current limit.
Photodiode feedback current
is out of range for the PLD
Refer to the laser diode datasheet to determine the approximate
photodiode (PD) current at the desired output power level. If the PD
current exceeds the PLD PD current range, set the PD Range switch
to High Range; see
page 12.
