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
