Business Wire
Fairchild Semiconductor�s (NYSE: FCS) FAN5350 has been named a Hot
100 Product of 2007 by EDN Magazine in the power semiconductors and
IC category. This revolutionary 3MHz/600mA DC/DC synchronous buck
converter features 16�A quiescent current, 20mV transient response
and low-voltage ripple. The FAN5350 is designed to power DSP core
processors, application processors and I/O interfaces, and utilizes
Fairchild�s proprietary new ultra-fast architecture specifically
designed to simultaneously provide industry-leading quiescent
current and transient-response performance. This high-performance,
compact converter enables designers to meet next-generation load
requirements while preserving battery life and saving board space
in cell phones, media players, GPS devices, Bluetooth headsets and
other single-cell 2.7V to 5.5V lithium-ion-powered portable
applications. �Fairchild�s FAN5350 datasheet shows an input voltage
or 2.7 to 5.5 volts and has a 1.82 volt fixed output,� commented
Paul Rako, EDN�s technical editor, in his July 2, 2007 blog. �What
is remarkable about this part is the 16 microampere quiescent
current while it operates at 3 MHz. The transient response is 20mV
to a 300 mA load step. It is these kind of remarkable specs that
make me wonder if the analog folks are going to make life pretty
difficult for the digital power crowd. In addition the part can get
up to 94 percent efficiency. Some companies play a game where they
spec efficiency with an inductor the size of a fist, but Fairchild
mentions that you can still get over 90 percent efficiency using a
1 uH chip inductor. Bravo.� Products selected for EDN�s annual Hot
100 Products issue are chosen by its editors from the hundreds of
newsworthy items that appear in the pages of EDN in print or
online. Eligible products must have appeared in EDN during the year
and could have been featured in EDN�s New Products section, a
feature story, or an online exclusive. EDN Editorial Director Maury
Wright stated, �Our editorial team covers new product introductions
on a daily basis and we see a lot of worthy products. We look back
once a year and choose the introductions that we believe will have
the greatest significance to the design engineer and create the Hot
100 list.� About Fairchild Semiconductor: Fairchild Semiconductor
