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 …

without Schottky Diodes
Introduction Inside the LTC3441
The LTC3441 patented control technique provides smooth and continuous
transfer from buck, buck-boost and
boost modes while maintaining a
constant frequency at no load. The
operating frequency is factory set to
1MHz and can be synchronized up to
1.7MHz. For light loads, the part offers
user controlled Burst Mode operation
to maximize battery life, drawing only
25ВµA of quiescent current. To limit
inrush current at start-up, an external
RC network can be connected to the
SHDN/SS pin to control output voltage rise time.
The LTC3441 is available in a small
3mm by 4mm low thermal resistance
12-lead DFN package. L1
