DESIGN IDEAS L A Complete 500mA Linear Charger
and 300mA Synchronous Buck
Converter in a Tiny 3mm Г— 3mm
by Ashish Kirtania
DFN Package
Introduction
The LTC4080 is a full-featured, singlecell 4.2V Li-Ion battery charger with
an integrated synchronous buck
DC/DC converter designed primarily
for handheld applications. Its tiny
3mm Г— 3mm DFN package and low
external component count provide
space-savings in todayвЂ™s crowded
circuit boards. The high operating
frequency (2.25MHz) of the switching
regulator minimizes overall solution
footprint further by allowing the use of
tiny, low proп¬Ѓle inductors and ceramic
capacitors. To extend battery life, the
buck regulator offers high efп¬Ѓciency
burst mode operation in which the DESIGN IDEAS
