DESIGN FEATURES Versatile Buck-Boost Converter
Offers High Efп¬Ѓciency in a Wide
by Dave Salerno
Variety of Applications
Introduction L1 5ВµH Miniature hard disk drives are a popular storage medium for MP3 music п¬Ѓles,
digital photographs and other data
stowed in the latest portable electronics. Likewise lithium-ion batteries are
popular for these same devices, which
presents a minor problem in that mini
disk drives typically require a 3.3V
supply, which is right in the middle
of the lithium-ion batteryвЂ™s operating
range (3.0V-to-4.2V). This requires a
converter that can both step down a
fully-charged Li-Ion battery and step
up the same battery as it discharges
to sub-3.3V levels.
The LTC3442 is a 1.2A buck-boost
converter that is ideal for mini disk
drive applications, and certainly for
other buck-boost appliations as well.
The LTC3442 extends battery life with
95% efп¬Ѓciency and п¬Ѓts into tight spaces …
