  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 …
