We see from your search that you're looking for information on the term "POL convertors",
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 DC/DC convertors provide power density boost from
FDK Corp, which we summarised at the time by saying "Senpai's new DC/DC convertors suit applications that require high efficiency, tight regulation and high reliability in elevated temperature environments".
Earlier in the week,
we featured the news release DC/DC convertors survive with minimal cooling from
FDK Corp: "The FPMR05SR75 10A Senpai DC/DC convertors provide tightly-regulated programmable output voltages in the range of 0.75 to 3.63V DC".
In July 2007, we covered the news from International Rectifier
concerning its IR3622MPbF and IR3622AMPbF
- take a look at Controllers ease POL convertor design
which says: "Dual-channel synchronous buck control ICs integrate high performance drivers for medium- to high-current point-of-load buck convertors".
Take a look also at the news release from Emerson Network Power - Embedded Power, MPU-controlled IBCs raise power efficiency,
as well as LDOs support Z-One digital power architecture from Micrel,
and Lambda exhibits innovations in power from Lambda.
