We see from your search that you're looking for information on the term "NPN",
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 January 2008, we covered the news from National Semiconductor
concerning its LME49600 audio buffer
- take a look at Buffer keeps noise out of audio applications
which says: "The LME49600 can respond to highly dynamic inputs, accurately reproducing these signals without degrading them by adding distortion".
Take a look also at the news release from National Semiconductor, Audio power amp ICs cut distortion,
as well as LED driver powers three strings of eight from Linear Technology Corp,
and IR LEDs and phototransistors in compact form from Pacer International.
