iC-WKM

M-TYPE CW LASER DIODE DRIVER

Rev C1, Page 1/9

FEATURES

o Optimised for M-type laser diodes

(single supply, case grounded)

o CW operation up to 350 mA from a single supply of 3.6 to 15 V

o Rapid soft start after power-on

o Simple power adjustment via an external resistor

o Integrated reverse polarity protection for the iC and laser diode

o Strong suppression of transients with small external

capacitors; integrated flyback path

o Permanent shutdown with excessive temperature and

overcurrent (i.e. if the laser diode is damaged or the feedback

current path fails)

o Two feedback inputs permit all current laser diode types to be

used (M/P/N configurations)

o Modulation via the feedback inputs possible

o Wide monitor current range from 2.5 µA to 6.25 mA

APPLICATIONS

o Blue laser diodes

o Laser diode modules

o Laser diode pointers

o Laser levels

o Bar-code readers
