DESIGN IDEAS Micropower SOT-23 Inverting DC/DC
Converter Extends Battery Life in
Space-Sensitive Applications by Eric Young
Introduction
Low power negative bias supplies are
commonly used in many of todayвЂ™s
handheld products for imaging and
display modules. As is the case with
all portable products, small size and
efп¬Ѓcient operation are top requirements. The LT3483 steps in to п¬Ѓll
this need with a minimum footprint,
low proп¬Ѓle negative supply that yields
long battery life.
One of the strengths of the LT3483
is its versatility. It can be used for
inverting step-up (boost) or for inverting step-down applications. It features
an input range of 2.5V to 16V, so
the device works well with a range of
battery types and conп¬Ѓgurations. Its
internal 40V switch and integrated 40V
Schottky rectiп¬Ѓer allow it to generate
output voltages to В±38V.
The LT3483 also includes features …
