High Efficiency USB Power Management System Safely Charges
Li-Ion/Polymer Batteries from Automotive Supplies вЂ“ Design Note 464
George H. Barbehenn
In this circuit, the LTCВ®4098 USB power manager/LiIon battery charger controls an LT3480 HV step-down
regulator. The LTC4098вЂ™s Bat-Trackв„ў feature provides
a high efп¬Ѓciency, low power dissipation battery charger
from low and high voltages alike. The Bat-Track feature
controls an internal input current-limited switching regulator to regulate VOUT to approximately VBAT + 0.3V which
maximizes battery charger efп¬Ѓciency, and thus minimizes
power dissipation by operating the battery charger with
minimal headroom. Furthermore, the Bat-Track feature
reduces charge time by allowing a charge current greater
than the USB input current limitвЂ”the switching regulator
behaves like a transformer exchanging output voltage for
output current. Introduction
Automotive power systems are unforgiving electronic
environments. Transients to 90V can occur when the
nominal voltage range is 10V to 15V (ISO7637), along with
battery reversal in some cases. ItвЂ™s fairly straightforward
to build automotive electronics around this system, but
increasingly end users want to operate portable electronics, such as GPS systems or music/video players,
and to charge their Li-Ion batteries from the automotive
battery. To do so requires a compact, robust, efп¬Ѓcient …

LвЂ‰DESIGN FEATURES 1.2A Monolithic Buck Regulator
Shrinks Supply Size and Cost with
Programmable Output Current Limit
by Tom Sheehan Introduction
Power supplies are often overqualified
for their job. This is because power
ICs often specify a current limit that
is more than twice the rated output
current of the device. The power supply
components are sized to handle the
maximum current that the IC can deliver, even if loads are unlikely to draw
that current during normal operation.
The components are bigger and more
expensive than they need to be.
There is, however, an alternative:
set an accurate maximum output current on the supply once the real world
load is known. Accurately setting the
maximum output current reduces the
required current rating of the regulatorвЂ™s power path components, thus
replacing big, expensive components
with smaller, less expensive ones.
A limit on the regulatorвЂ™s maximum output limits the maximum power
dissipation of both the supply and …
