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 Specifi cation. If exposed to stress
above these limits, function and performance may degrade in an
unspecifi ed manner.
Confi guration File
This product is designed with a digital control circuit. The control
circuit uses a confi guration fi le which determines the functionality
and performance of the product. The Electrical Specifi cation table
shows parameter values of functionality and performance with the
default confi guration fi le, unless otherwise specifi ed. The default
confi guration fi le is designed to fi t most application needs with focus
on high effi ciency. If different characteristics are required it is pos-
sible to change the confi guration fi le to optimize certain performance
characteristics. Note that current sharing operation requires changed
confi guration fi le.
In this Technical specifi cation examples are included to show the
possibilities with digital control. See Operating Information section for
information about trade offs when optimizing certain key performance
characteristics.
