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, MaxwellвЂ™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 heatвЂ”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 …
