We see from your search that you're looking for information on the term "Inductor",
and we have a large number of manufacturers' news releases and technical articles here on Electronicstalk which will be of interest.
Let me be your guide.
Start with
the news release LED drivers cover all the latest options from
Zetex, which we summarised at the time by saying "Inductive DC/DC convertors drive single or multiple LEDs with currents from 700mA through to 1.5A, in buck, boost and buck/boost configurations".
Earlier in the week,
we featured the news release Step-down regulator handles automotive extremes from
Linear Technology Corp: "The LT3500 runs from an input voltage range of 3 to 36V (40V maximum), making it ideal for load dump and cold-crank conditions found in automotive applications".
In February 2008, we covered the news from Linear Technology Corp
concerning its LT1938
- take a look at Step-down regulator majors on efficiency
which says: "Special design techniques enable high efficiency over a wide input voltage range".
Take a look also at the news release from Linear Technology Corp, Regulator goes up or down with only an inductor,
as well as Smaller format for ferrite inductors from Murata Electronics (UK),
and Convertors boost single cells to 5.25V from Linear Technology Corp.
