3A Monolithic Buck Regulator in 4mm x 4mm QFN &mdash LT Journal
PDF, 535 Kb, File published: Mar 28, 2006
Extract from the document
L DESIGN FEATURES Introduction
The LTC3412A is much more than a
drop-in replacement for the popular
LTC3412 monolithic buck switching
regulator. Though still offered in a
thermally enhanced 16-lead TSSOP,
the LTC3412A is also squeezed into
a smaller footprint 4mm Г— 4mm
QFN, reducing the package height to
0.75mm from 1.1mm. At the same
time, the maximum load current has
risen to 3A from the LTC3412вЂ™s 2.5A,
and the minimum input voltage has
been pared down to 2.25V from the
earlier 2.625V. The LTC3412A can
still deliver efп¬Ѓciency as high as 95%,
accept input voltages up to 5.5V, and
switch at frequencies up to 4MHz,
making it a compact and efп¬Ѓcient
solution for portable electronics that
require low supply voltages (down to
0.8V) converted from typical battery
voltages. …
