DESIGN FEATURESвЂ‰L Highly Integrated USB Power Manager
with Li-Ion Charger and Three
Step-Down Switching Regulators
in 4mm Г— 4mm QFN
by Amit Lele
Introduction
Mobile technology has radically
changed the way we acquire, share
and disseminate information. Modern,
feature-rich handheld and portable
devices require several power management circuits, including a battery
charger, multiple step-down switching
regulators and low power LDOs for
watchdog circuitry. If each of these
functions is served by a separate power
supply IC, each IC (and its external
components) occupies valuable board
space, consumes battery-draining
quiescent current and significantly
increases the overall development and material costs of the device. The
LTC3557 solves this problem by bringing all power management functions
into a single device. It combines a full
featured USB power manager, a Li-ion …

Less Than 20mm2
Introduction
The quickest way to build an efficient
power system for a battery-powered
portable application is to use an
IC that combines all power control
functions into a single chip, namely a
Power Management Integrated Circuit
(PMIC). PMICs seamlessly manage
power flow from various power sources
(wall adapters, USB and batteries) to
power loads (device systems and the
charging battery), while maintaining
current limits where required (such
as that specified for USB). To this
end, PMICs typically feature built-in
PowerPathв„ў control, DC/DC conver-USB/WALL
