Optimised for P-type laser diodes (case grounded)
CW operation up to 350 mA from 3 to 15 V supply voltage
Rapid soft start after power-on
Simple power adjustment via an external resistor
Control loop accuracy better than 2% with changes in
temperature, supply voltage and load current
Integrated reverse polarity protection for the iC and laser diode
Strong suppression of transients with small external
capacitors; integrated flyback path
Permanent shutdown with excessive chip temperature and
overcurrent (i.e. if the laser diode is damaged or the feedback
current path fails)
Second feedback input MDA also permits the operation of
N-type laser diodes
Modulation via the feedback inputs possible
Wide monitor current range from 2.5 µA to 6.25 mA
