DESIGN IDEAS Inductorless, Efficient Step-Down
DC/DC Converter Provides Dual
Low Noise Outputs in Spaceby Bill Walter
Constrained Designs
Introduction Increase Battery Run Time Linear TechnologyвЂ™s new LTC3252
switched capacitor step-down DC/
DC converter squeezes dual adjustable outputs into a space saving 3mm
by 4mm DFN package. Each output is
programmable within a range of 0.9V
to 1.6V, is capable of 250mA of current, and operates from a single 2.7V
to 5.5V supply. To keep the converter
footprint small, the LTC3252 operates
at high frequency, allowing the use of
tiny low cost ceramic capacitorsвЂ”no
inductors are required. The LTC3252 also features Burst
ModeВ® operation, which allows the
LTC3252 to achieve high efficiency
even with lightly loaded outputs. While
in Burst Mode operation the LTC3252
delivers a minimum amount of charge
for a few cycles then goes into a low
current state until the output drops
enough to require another burst of …
