CW Laser Diode Driver, Optimized for P-Type Laser Diodes

iC-WKP is a driver for laser diodes in continuous wave (CW) operation with laser currents of up to 350 mA from a wide power supply range of up to 15 V which requires only four external components. The driver is optimised for P-type laser diodes and allows the connection of the laser diode case to ground.

The iC includes a soft start of the regulator to protect the laser diode when the power supply is switched on. The iC also filters the laser diode power supply for transients.
