  How to Choose Cool Running, High Power, Scalable POL
  Regulators and Save Board Space
  Afshin Odabaee The art of designing efficient and compact
  DC/DC converters is practiced by a select group
  of engineers with a deep understanding of the
  physics and supporting mathematics involved in
  conversion design, combined with a healthy dose
  of bench experience. A deep understanding of
  Bode plots, Maxwell’s equations and concerns
  for poles and zeros figure into elegant DC/DC
  converter design. Nevertheless, IC designers often
  escape dealing with the dreaded topic of heat—a
  job that usually falls to the package engineer.
  Heat is a significant concern for point-ofload (POL) converters, where space is tight
  among delicate ICs. A POL regulator generates heat because no voltage conversion
  is 100% efficient (yet). How hot does the
  package become due to its construction,
  layout and thermal impedance? Thermal
  impedance of the package not only raises
  temperature of the POL regulator, it also
  increases the temperature of the PCB and
  surrounding components, contributing
  to the complexity, size and cost of the …
