iC-WKM M-Type CW Laser Diode Driver
Applications
- Blue laser diodes
- LD modules
Features
- Optimised for M-type laser diodes (single supply, case grounded)
- CW operation up to 350 mA from a single supply of up to 15 V
- Rapid soft start after power-on
- Simple power adjustment via an external resistor
- Control loop accuracy better than 3% 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
- 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 2.5 ľA to 6.25 mA
