L DESIGN IDEAS Tiny Buck-Boost Converter for
Low Current Applications by Eddy Wells Introduction
One common challenge for many battery powered portable applications is
creating a regulated output voltage
above or below the input source. Traditional buck-boost approaches, such
as a dual inductor SEPIC converter or
cascaded regulators, are unacceptable
in most portable devices because of
their large solution size and low efп¬Ѓciency. Smaller footprint, integrated
charge-pump solutions can switch
between buck and boost operation, but
charge-pumps achieve good efп¬Ѓciency
at only a few operating voltages, while
efп¬Ѓciency dips below 50% at others.
Another compact and simple approach
forgoes a portion of the battery capacity and uses a buck (step-down) only
solution, but the advantages are hard
to justify when much of the battery
capacity is not used, as with certain
Li-Ion chemistries and a 3.3V output,
or with two alkaline cells and a 3.0V
or 2.5V output. two small ceramic capacitors, a miniature inductor, and the ThinSOT IC.
All versions of the part are available …
