DESIGN IDEAS Efficient, Flexible Boost Converter Fits
into Charge-Pump Footprint by Eddy Wells
Introduction Handheld devices often use low
power step-up DC/DC converters to
power displays, LEDs and I/O circuitry, or to charge alternate power
sources. Capacitive charge-pumps
or inductor-based boost converters
are the two most common solutions
to step-up conversion, and each has
certain advantages and trade-offs. A
charge-pump converter offers a simple,
compact solution, but it has a limited
range of VIN to VOUT ratios, such as 3.3V
to 5V. A traditional boost converter
offers more efficient operation and a
greater range of step-up ratios, but
boost solutions typically take more
space, and systems issues such as
inrush current and short circuit protection are often solved with added
external circuitry.
The LTC3459 is a small, synchronous boost converter that addresses
many issues found in a traditional
boost converter. The LTC3459 offers Burst Mode operation for high …
