1.5A Monolithic Buck-Boost DC/DC Converter with
Up to 95% Efficiency Features 2.5VвЂ“15V Input and Output
Voltage Ranges
Richard Cook Multicell high capacity batteries are increasingly becoming
commonplace in handheld devices and industrial
instruments that receive their power from a variety of
sources. To maximize battery run time and support the
variety of power sources, voltage regulators in multipower
source systems must be able to maintain a constant output
voltage even as the input voltage source resides above,
below or equal to the output. This can be accomplished
using two separate power converters with two controller
ICs. A better solution is to use a single buck-boost DC/DC
converter, which offers a smaller, simpler and more efficient
design, attributes critically important in handheld devices.
The LTC3111 is a monolithic buckboost converter with input and output
voltage ranges of 2.5V to 15V and an
output current capability of 1.5A. It
allows conversion from a variety of
power sources such as single or multi
Li-ion cells, lead acid batteries, capacitor banks, USB cables or wall adapters. architecture, effectively eliminating jitter
and EMI that can occur when crossing the
boundary between step-up and step-down …
