DESIGN FEATURES No Space? No Problem for these Tiny,
Inductorless, Efficient, Low Noise, 1.8V
and 1.5V, Step-Down DC/DC
by Bill Walter
Converters
Introduction
The proliferation of portable devices
with ever increasing functionality has
imposed a higher demand on power
conversion circuitry, with a continued emphasis on maximizing battery
life while reducing board real estate.
The new LTC1911 Step-Down DC/
DC converter helps designers make
extremely small conversion circuits
while maintaining the high efficiencies needed to extend battery life. The
LTC1911 saves space by operating at
high frequency, allowing the use of
tiny low cost ceramic capacitorsвЂ”no
inductors required. The LTC1911 also
comes in a low profile (1.1mm) MSOP8 package. Figure 1 shows just how
small the conversion circuit can beвЂ”
a complete converter takes less than
0.08in2 of board space. Its small size …
