iC-WKP P-Type CW Laser Diode Driver, Optimized for P-Type Laser Diodes
|
|
| Applications |
- Laser diode modules
- Laser diode pointers
- Pilot lasers
- Laser levels
- Barcode readers
- Distance measuring sensors
|
|
| Features |
- 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 ľA to 6.25 mA
