We see from your search that you're looking for information on the term "Thermistor",
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".
A couple of weeks before,
we featured the news release Laser pump diodes power up to 10W from
Pacer International: "Target industrial markets include pumping fibre lasers, diode-pumped solid state lasers, uncooled fibre amplifier and direct material processing".
In January 2008, we covered the news from Pacer International
concerning its AM6-808B and AM6-808BW laser pump diodes
- take a look at Laser pump diodes provide tight bandwidth
which says: "A new series of laser pump diodes from Alfalight , the AM6-808B and AM6-808BW, provides 5 W of 808nm light output with a 200 um 0.15 NA fibre".
Take a look also at the news release from Pacer International, Laser pump sources offer long lifetimes,
as well as Laser modules offer high brightness with low power from Intense,
and Power manager takes charge of USB devices from Linear Technology Corp.
