  advertisement Shrink Battery-Powered Products with a Combination Battery
  Charger and DC/DC Converter – Design Note 1002
  Tom Hack
  Introduction
  Until now, power management in portable devices or
  systems with battery backup have required a mix of
  major components to fulfill the basic functions of battery
  charging and generation of system supply voltages. A
  typical solution requires at least one charger IC for
  charging the battery, another IC to supply a regulated
  system bus voltage from a constantly changing battery
  voltage, PowerPathв„ў control and a low dropout regulator (Figure 1).
  Space is at a premium in these ever shrinking portable
  products, creating an imperative to shrink the power
  circuitry as well. The LTCВ®1980 solves the space problem
  by combining these functional blocks into a single IC. The
  result is a substantial reduction in the complexity of
  portable power systems (Figure 2).
  How the LTC1980 Reduces Size and Cost
  The LTC1980 manages both battery charging and
  generaton of the regulated system bus voltage via a unique
  bidirectional pulse-width modulator design (Figure 3).
  When the wall adapter is present, power passes directly to …

  Introduction
  Until now power management in
  portable devices has required a mix
  of major components to fulfill the basic functions of battery charging and
  generation of system supply voltages.
  A typical solution requires at least two
  major devices (and associated external components): one charger IC for
  charging the battery and another IC
  to supply a regulated system bus voltage from a constantly changing battery
  voltage. The LTC1980 is a single-device
  solution that manages both battery
  charging and generation of the regulated system bus voltage. way through the converter, a fact that
  is exploited to charge or discharge the
  battery, depending on the power needs
  of the system.
  The battery charger portion of the
  LTC1980 is a full-featured, constant
  current, constant voltage, Li-Ion
  charger with timer termination. The …
