As portable devices begin to overtake the PC-centric world, it
is increasingly important that cell phones, smartphones, digital
cameras and other devices are able to communicate with each other.
To enable this, Fairchild Semiconductor’s (NYSE: FCS) FAN4860, a 5V
300mA TinyBoost™ regulator offers power for USB On-the-Go (OTG) and
HDMI communication circuits, combining a high level of efficiency
as well as a small form factor.
This device switches at a high 3MHz frequency, allowing the use
of small capacitors and inductors, saving board space in
space-constrained designs and reducing overall Bill of Material
(BOM) costs. Available in two package options, WL-CSP (0.88 x
1.23mm) and ultra-thin MLP (2 x 2mm), the FAN4860 has a total
solution area as small as 2.2 x 3.9mm.
This regulator offers the industry’s highest efficiency for this
form factor, extending battery life through an optimized power
train and low quiescent current. With a VIN of 3.6V at light load
(1mA), efficiency is 84 percent and at 200mA load efficiency is 91
percent. In addition, the true load-disconnect between the battery
and the load eliminates the leakage from the battery during the OFF
state, extending the phone’s shutdown life. The FAN4860 also offers
excellent transient response even with a small output
capacitor.
This easy-to-design solution supports the quick design cycles
found in the mobile device market, making it an ideal choice for
cell phones, smartphones, PMPs and lithium-ion portables.
The FAN4860 is another example of Fairchild’s broad solutions
that extend battery life and conserve board space in portable and
consumer designs. With a substantial portfolio of analog and power
IP, along with system-level expertise, Fairchild develops solutions
that define both user satisfaction and market success. The FAN4860
complements Fairchild’s core power and battery management
solutions, including the FAN5361 – a 6MHz 600mA Buck regulator,
which allows the use of tiny 470nH chip inductors and 0402 case
size input and output capacitors, as well as the award-winning
FAN5355 – an 800mA/1000mA 3MHz Buck converter equipped with an I2C
interface for dynamic voltage scaling.
