DESIGN IDEASвЂ‰L Synchronous Boost Converter with
Fault Handling Generates 5V at
500mA in 1cm2 of Board Space
by Eddy Wells Introduction Lithium-Ion to 5V, 2.5W
Converter current. Requiring only an inductor
and input/output filter capacitors,
the entire converter occupies only
about 1cm2 of board space. The IC
includes internal compensation, the
output divider, and soft-start circuitry
to minimize external components. In
shutdown, the LTC3529 disconnects
the output from the input and draws
less than 1ВµA from the source.
In fixed frequency PWM mode, the
efficiency for a typical Li-Ion source to
5V peaks at 92%, as shown in Figure
4, and remains above 80% for load currents greater than 30mA. The LTC3529
delivers up to 500mA of current at a
5V output and is therefore suitable for
both low and high power USB applications. As with any DC/DC converter,
a tradeoff exists between switching
