design features 15V, 2.5A Monolithic Buck-Boost DC/DC Converter with
95% Efficiency and Low Noise Operation
Eddy Wells Power-hungry handheld devices and industrial instruments often require multicell or high
capacity batteries to support their ever-increasing processing needs. A wide voltage range,
high efficiency buck-boost DC/DC converter is the ideal solution for longer battery run
times and handling multiple input sources. The LTC3112 is a 2.2V to 15V input capable
2.5A buck-boost converter. The extended voltage range allows conversion from a variety of
power sources such as one, two or three Li-ion cells, lead acid batteries, supercapacitors,
USB cables and wall adapters to output voltages programmed between 2.5V and 14V.
The LTC3112 features the latest generation
buck-boost PWM control scheme, effectively eliminating jitter when crossing the
barrier between buck and boost operation. Safeguards such as current limit,
overvoltage protection, thermal shutdown,
and short-circuit protection provide
robust operation in harsh environments.
For demanding applications where component size or conversion efficiency is critical, the LTC3112вЂ™s 750kHz default switching
frequency can be synchronized between
300kHz and 1.5MHz. For designs where
output current needs to be controlled
or measured, an output current monitor
pin is available. Selectable Burst ModeВ®
operation extends the operating life when
the battery-powered device is idle. …
