iC-WKP - P-Type CW Laser Driver

APPLICATIONS

• LD modules
• LD pointers
• Pilot lasers
• Laser levels
• Barcode readers
• Distance measuring sensors

FEATURES

• Optimised for P-type laser diodes (case grounded).
• CW operation up to 350mA from 3 to 15V supply voltage.
• Rapid soft start after power-on.
• Simple power adjustment via 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 LD.
• 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 permits operation of both P and N type laser diodes.
• Modulation via the feedback inputs is possible.
• Wide monitor current range from 2.5µA to 6.25mA.
