Fairchild Semiconductor (NYSE: FCS) provides the industry�s
smallest power management solution for the designers of 3G handsets
and wireless datacards. The FAN5902, RF Power DC-to-DC converter,
is packaged in a 12 bump, 0.5mm pitch CSP package and operates at
6MHz with a reduced size 0.5uH chip inductor, saving space and
component costs. This converter helps to extend talk-time by up to
40 minutes in 3G handsets by adapting the voltage supply level of
the 3G RF power amplifier according to the RF power sent through
the antennae, enabling higher power efficiency for a wide range of
antenna power levels. This results in up to 100mA of battery
current consumption savings in data-centric and smart phones
especially in suburban and poor coverage areas. This feature
enables 20 to 30 percent more power, dramatically extending
connection time and allowing 3G handsets to run more processor
applications. In addition, the FAN5902 offers up to 800mA rms
current output capability to service excessive RF PA current
resulting from strong antenna mismatch and a 50 milliohm on
resistance bypass FET, enabling operation down to 2.7 volts.
The FAN5902 also addresses the key problem of overheating in the
RF power amplifier, especially at high battery voltage. Since the
FAN5902 scales down the RFPA supply voltage, reducing its heating
by 20 to 40 percent, the heat sink can be shrunk and the component
density can be increased, reducing weight, cost and size.
Fairchild Semiconductor continues to innovate mobile designs
with its wide range of solutions that answer compelling design
challenges of increasing efficiency, reducing board space,
preserving signal fidelity and simplifying design. This includes
the FAN5355, an 800mA/1000mA, 3MHz Buck converter, developed for
powering core graphics and application processors in handheld
applications where footprint, wide-range efficiency and performance
are important, and the FAN5361, a 6MHz, 600mA Buck converter that
offers an optimal balance between efficiency and size for portable
applications.
