DESIGN IDEASвЂ‰L USB Compatible Li-Ion Battery
Charger and Dual Buck Regulators
in a Single 3mm Г— 3mm QFN
by Aspiyan Gazder Introduction
Manufacturers of handheld devices
such as MP3 players are always looking to reduce system size and cost,
even as they increase performance
and functionality. The only way to do
so is to integrate functions at the IC
level. For applications powered from
a single Li-Ion cell, the LTC3559
provides a single chip solution that
charges a Li-Ion cell while efficiently
generating two supply voltage rails to
power the device.
The LTC3559 is a USB compatible
battery charger and two monolithic
synchronous buck regulators integrated into a low profile 3mm Г— 3mm
16-lead QFN package. The battery
charger has all the features that a
stand alone battery charger might
offer, such as an NTC input for temperature qualified charging, internal
timer termination and bad battery …

LвЂ‰DESIGN FEATURES New Family of Integrated Power
Controllers Combine Fast Battery
Charging, PowerPath Control and
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
