DESIGN IDEASвЂ‰L 94% Efficient, Low Noise, Step-Up
DC/DC Converter in 2mm Г— 2mm
DFN Package Offers Unrivaled
Performance and Solution Size
by Bert Hepfinger Introduction
As handheld electronic devices shrink,
the need for compact, high efficiency
power converter solutions grows. The
new LTC3427 is a full featured, low
noise, step-up converter that is ideal
for space constrained applications. It
integrates a fixed frequency, internally
compensated, synchronous boost converter with output disconnect, inrush
current limiting and soft start into a
low profile 0.75mm Г— 2mm Г— 2mm
DFN package. A switching frequency
of 1.25MHz minimizes the solution
footprint by allowing the use of tiny,
low profile inductors and ceramic
capacitors. The LTC3427вЂ™s fixed frequency operation makes it ideal for
noise sensitive applications where the
wide frequency spectrum associated
with multiple mode converters may …
