The inductors selected are a standard inductor
with thin metal underpass, a MLP multilayer inductor with 9 [micro]m thick spiral metallization and a 3-D inductor.
Advanced control architecture allows designers to further enhance the efficiency by 4 percent through the use of a standard inductor
Primarion's proven technology offers the highest efficiency in the industry to-date and is the only solution that combines the innovative digital control technique and non-proprietary standard inductor
based buck converter topology.
With all of these technology attributes, a Q of 17 can be achieved for a 1 nH inductor at 5 GHz by using a standard inductor
device from the device library.
Another solution is to use two standard inductors
Use of standard inductors
or transformers available from National's magnetics partners precludes the need for any magnetics design.
