Monolithic Linear Battery Charger Operates from Inputs Up
to 60V
Design Note 535
Joshua Yee
Introduction
For charging relatively low capacity batteries, or
maintenance charging backup and keep-alive batteries,
linear topology battery chargers are valued for their
compact footprints, simplicity and affordability. Even
so, there is a dearth of linear chargers that accept a
10V or higher input voltage, leaving many industrial
and automotive systems underserved.
Some switch mode solutions can accept high input
voltages and switching topologies offer current and
efficiency advantages, but they also incur significant
costs in complexity and solution footprint. In the end,
a switch mode solution is usually overkill for the low
currents necessary in keep-alive systems or backup
battery chargers. Furthermore, few are suitable for
automotive and industrial applications up to 60V.
LTC В®4079 is a wide input range standalone charger
that can be powered by any DC source from 2.7V up
to 60V, enabling CC/CV charging directly from 12V and …
