We see from your search that you're looking for information on the term "Pb-free",
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 Switching regulator is cool alternative to linear from
Linear Technology Corp, which we summarised at the time by saying "Complete DC/DC module includes a DC/DC controller IC, power switches, inductor, compensation circuitry and input and output bypass capacitors".
The same day,
we featured the news release Transmitter module saves space and power from
RF Micro Devices: "Dual-band transmit module features two symmetrical receive ports, 50ohm matched input and output ports and GSM/GPRS Class 12 compliance".
In January 2008, we covered the news from Advanced Analogic Technologies
concerning its AAT1239-1
- take a look at White LED driver cuts down on flicker
which says: "By driving up to 10 white LEDs in a serial string, the AAT1239-1 simplifies the use of larger LCD panels in a wide array of battery-powered portable devices".
Take a look also at the news release from Micrel, Hot-swap controllers meet PCIe specs,
as well as Integrated switches simplify power design from Advanced Analogic Technologies,
and Polymer tantalum chips are rated for 35V from Kemet Electronics Corp.
