design features 3A Output, 96% Efficient Buck-Boost DC/DC Converter
Sets the Standard for Power Density and Noise Performance
Richard Cook High power density has become a primary requirement
for DC/DC converters, as they must keep up with ever
increasing functional density of electronics. Likewise, power
dissipation is a major concern for todayвЂ™s functionally rich,
tightly packed devices pushing the need for highly efficient
solutions to minimize temperature rise. For applications
where the input voltage source can be above or below
the regulated output voltage, finding an efficient compact
solution can be a challenge, especially at elevated power
levels. Conventional design approaches, such as using
a dual inductor SEPIC converter, produce relatively
low efficiencies and relatively large solution sizes.
The LTC3113 single inductor buck-boost
converter offers a compact, highly efficient alternative. Internal low resistance
switches allow the converter to support
an impressive 3A of load current in a tiny
4mm Г— 5mm package. The LTC3113 offers
an extended input and output operating voltage range from 1.8V to 5.5V, with
peak efficiencies reaching 96%. The
internal PWM controller is designed for
low noise performance and offers a seamless transition between buck and boost …
