Absolute Maximum Ratings, sometimes referred to as no destruction limits, are normally tested with one parameter at a time exceeding the limits in the Electrical Speci cation. If exposed to stress above these limits, function and performance may degrade in an unspeci ed manner. Con guration File This product is designed with a digital control circuit. The control circuit uses a con guration le which determines the functionality and performance of the product. The Electrical Speci cation table shows parameter values of functionality and performance with the default con guration le, unless otherwise speci ed. The default con guration le is designed to t most application needs with focus on high ef ciency. If different characteristics are required it is possible to change the con guration le to optimize certain performance characteristics. Note that current sharing operation requires changed con guration le.
