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. See application notes
AN307 and AN312 for further information.
In this Technical specification examples are included to show the possibilities with digital control. See Operating Information section for information about tradeoffs
when optimizing certain key performance characteristics.
