Product Overview

The IC-SY WK2D evaluation board is a driver for laser diodes in continuous wave operation which requires only four external components. The wide power supply range of 2.4V to 6 V and the integrated reverse battery protection allow for battery operation with a minimum of two cells. A reversed battery connection destroys neither the IC nor the laser diode. The IC includes integrated circuitry protecting against destruction by ESD, excessive temperature and over current and a soft start which regulates the power and protects the laser diode when the power supply is switched on. The IC also filters the laser diode power supply for transients. The power supply is regulated and adapted to the laser diode used by an external resistor at MDA. The monitor current acts as a reference and is regulated independent of the influence of temperature and supply voltage (range: 10µA to 2.5mA).
  • Control loop accuracy better than 1% with changes in temperature, supply voltage and load current
  • IC-WK with additional spike detection at monitor input MDA
  • Integrated reverse polarity protection for the iC and laser diode
  • Modulation via the feedback inputs is possible
  • Rapid soft start after power on typical within 70s
  • Simple power adjustment via the external resistor
  • Strong suppression of transients with very small external capacitors, integrated flyback path
  • Two feedback inputs permit all current LD types to be used (N/P/M configurations)
  • Wide monitor current range from 10µA to 2.5mA
