Efficient DC/DC Converters in
by Sam Nork
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
