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 managementвЂ”how do
you meet increasing performance demands while keeping
a compact and small product cool in the userвЂ™s hand? small 1206-size 10ВµF ceramic capacitors, and a few other
tiny components. Furthermore, even simpler conп¬Ѓgurations 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 efп¬Ѓciency 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
solutionвЂ”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 …
