N-型CW激光管驱动器, 优化N-型激光管

Features      

• CW operation up to 300 mA from 2.4 to 15 V supply voltage

• Rapid soft start after power-on

• Simple power adjustment via an external resistor

• Control loop accuracy better than 1.5% 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

• 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 2.5 μA to 6.25 mA

Applications         

• Laser pointers

• LD modules

• Laser levels

• Barcode readers

• Distance measuring sensors
