1. Thermal Design
Verify that the Internal Heat Dissipation for your application does not exceed the maximum allowed.
The Safe Operating Area chart details the location of this limit.
Online, at

, choose the model
of QCL driver you will be using. Enter your power supply and QCL characteristics to determine internal
power dissipation with your design. Alternately, you can use the SOA charts in Appendix A and
manually draw your system load line. Airfl ow is required in some cases.
Note that the FAULT LED will light and the output current will be disabled if the internal temperature of
the driver exceeds safety limits.
