‘Inductor’
An Electronicstalk guide
Start with the news release
Fan5902 extends 3G handsets' talk time by 40mins from
Fairchild Semiconductor, which we summarised at the time by saying "Fairchild Semiconductor has introduced the Fan5902, a tiny power-management solution for designers of 3G handsets and wireless datacards.".
Several months prior to that,
we featured the news release ADP1655 brightens digital-camera flashes from
Analog Devices: "Analog Devices has released a dual-white LED flash driver for battery-operated digital cameras that increases flash brightness to more than 200 lumens and improves picture quality. ".
In July 2009, we covered the news from DMTL
- take a look at Surface-mount inductors available from DMTL
which says: "A range of low-profile surface-mount inductors from Coilmaster Electronics is now available from DMTL.".
Take a look also at the news release from Linear Technology Corp, DC/DC converter for GSM and GPRS cards,
as well as DC/DC converter launched by Ericsson from Ericsson Power Modules,
and Intersil releases ISL8201M power-converter from Intersil.
