LвЂ‰DESIGN FEATURES Tiny High Efficiency 2A Buck
Regulator Directly Accepts
Automotive, Industrial and
Other Wide Ranging Inputs
Introduction 2.4MHz by using a resistor tied from
the RT pin to ground. This allows a
trade off between component size and
efficiency. The switching frequency
can be synchronized to an external
clock for noise sensitive applications.
An external resistor divider programs Automotive batteries, industrial power
supplies, distributed supplies and
wall transformers are all sources of
wide-ranging, high voltage inputs. The
easiest way to step down these sources
is with a high voltage monolithic stepdown regulator that can directly accept
a wide input range and produce a
well-regulated output. The LT3480 is a
new step-down regulator that accepts
input from up to 38V (60V transient)
while providing excellent line and load
regulation and dynamic response. The
LT3480 offers high efficiency solutions …
