2.4V CW LASER DIODE DRIVER
FEATURES
° CW operation up to 60mA from 2.4..6V supply voltage
° Rapid soft start after power-on
° Simple power adjustment via the external resistor
° Control loop accuracy better than 1% 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 protects against transients
° 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
(M/P/N configurations)
° Modulation via the feedback inputs is possible
° Wide monitor current range from 10µA to 2.5mA
° Extended temperature range available as an option
Rev A1, Page 1/12
APPLICATIONS
° Battery-powered LD modules
° LD Pointers
