1ВµA IQ Synchronous Boost Converter Extends Battery Life in
Portable Devices
Design Note 516
Goran Perica
Introduction
Boost converters are regularly used in portable devices to produce higher output voltages from lower
battery input voltages. Common battery configurations include two to three alkaline or NiMH cells or,
increasingly, Li-Ion batteries, yielding a typical input
voltage between 1.8V and 4.8V. Because the batteries used in portable devices are
usually as small as possible, they present high internal impedance under heavy loads, especially close to
the end of their discharge cycle. Unlike other boost
converters that struggle with high source impedance
at startup, the LTC3122 prevents high surge currents
at startup. The 12V output converter shown in Figure 1 is designed
to run from any typical small battery power source. This
design centers around the LTCВ®3122 boost converter,
which can efficiently generate a regulated output
up to 15V from a 1.8V to 5.5V input. The LTC3122
includes a 2.5A internal switch current limit and a full
complement of features to handle demanding boost
applications, including switching frequency programming, undervoltage lockout, Burst ModeВ® operation or
continuous switching mode, and true output disconnect.
