  advertisement Handheld High Power Battery Charger
  Design Note 393
  Mark Gurries
  Introduction
  As the performance of many handheld devices approaches
  that of laptop computers, design complexity also increases. Chief among them is thermal management—how do
  you meet increasing performance demands while keeping
  a compact and small product cool in the user’s hand? small 1206-size 10µF ceramic capacitors, and a few other
  tiny components. Furthermore, even simpler configurations are possible (see Figure 2). This monolithic 2A,
  1.5MHz synchronous PWM standalone battery charger
  is packaged in a 4mm Г— 4mm 16-pin QFN package,
  which contains the built-in switching MOSFETs and
  charge termination controller. Figure 3 shows an actual
  PCB solution. For instance, as battery capacities inevitably increase,
  charge currents will also increase to maintain or improve
  their charge times. Traditional linear regulator-based battery chargers will not be able to meet the charge current
  and efficiency demands necessary to allow a product to
  run cool. What is needed is a switching-based charger
  that takes just about the same amount of space as a linear
  solution—but without the heat. Advanced Features and Functions
  One of the more unique features of the LTC4001 is its
  full remote voltage sense capability which permits faster
  charge rates by bypassing voltage drops in narrow PCB …
