15 V CW LASER DIODE DRIVER
FEATURES
BLOCK DIAGRAM
GND
+2.4..+15 V
CW operation up to 300 mA from 2.4 to 15 V supply voltage
Rapid soft start after power-on typical within 70 µs
Optimised for N-type laser diodes
Simple output power adjustment via an external resistor (APC)
Power control loop accuracy better than 1.5 % with changes in
temperature, supply voltage and load current
Integrated reverse polarity protection for the iC and laser diode
Strong suppression of transients with very small external
capacitors; integrated flyback path
Permanent shutdown with excessive temperature and
overcurrent (i.e. if the laser diode is damaged or the feedback
current path fails)
Two feedback inputs permit all current LD types to be used
(N/P/M configurations)
Modulation via the feedback inputs is possible
Wide monitor current range from 2.5 µA to 6.25 mA
Pin compatible to iC-WK and iC-WKL (SO8 package)

... In the event of failure, such as overcurrent in the laser path due to a lack of feedback, for example, a quick power lockout is activated. The shutdown persists until power is reapplied, permitting a restart. The strain on power packs and batteries is relieved and the laser class is retained even in the event of a dis- turbance ...
