DESIGN IDEAS Low Output Voltage Synchronous
Boost Regulators Extend Battery Life in
by Mark Jordan
Single Cell Applications
Introduction
3.3V OUTPUT
90% EFFICIENT The LTC3423 and LTC3424 Synchronous Boost Regulators are designed
for single cell (Alkaline, NiMH, or NiCd)
portable electronics that require a
low voltage supply, typically between
1.5V to 2.5V, at load currents up to
0.8 amps. These products are designed to prolong battery life for
applications where an available higher
voltage supply (2.7V to 5.5V) can provide internal bias for the IC. Before
the LTC3423 and LTC3424 became
available, power supplies for low voltage, high current solutions included
a buck converter from the higher voltage output, a simple, but relatively
inefficient solution. These new devices offer a solution that is just as
simple, but with much improved efficiency. The simple block diagrams in
Figures 1A and 1B show how this
difference arises: double conversion
is shown Figure 1A, and the approach
of regulating the low voltage supply …
