LвЂ‰DESIGN IDEAS Complete Power Solution for Digital
Cameras and Other Complex
Compact Portable Applications
by Brian Shaffer Introduction
Digital cameras, portable GPS systems,
MP3 players and other feature-rich
mobile devices have complicated
power requirements. In these complex
devices, the flow of power must be
carefully managed between a number of specialized sources and loads,
including charging/discharging the
battery, current-limited USB power
and a set of multivoltage power supply rails, including negative rails for
CCDs or LCDs. The supply rails must
be sequenced and tracked and faults
must be handled cleanly and communicated to a microcontroller.
When these requirements are
added together, the task of squeezing
an efficient and robust power system
into a handheld device can seem near
impossible. Linear Technology solves
this problem with a family of devices
called PMICs (Power Management Integrated Circuits) that greatly simplify …

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
