Notes:

Stress in excess of Absolute Maximum Ratings may cause permanent damage. 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 Specification. If exposed to stress above these limits, function and performance

may degrade in an unspecified manner.

Configuration File

This product is designed with a digital control circuit. The control circuit uses a configuration file which determines the

functionality and performance of the product. The Electrical Specification table shows parameter values of functionality

and performance with the default configuration file, unless otherwise specified. The default configuration file is designed

to fit most application needs with focus on high efficiency. If different characteristics are required it is possible to change

the configuration file to optimize certain performance characteristics. Note that current sharing operation requires changed

configuration file.
