1.1 L = 2.2ВµH IOUT(MAX) (A) Even as cell phones, computers
and PDAs shrink, they require an
increasing number of power supply
voltages. The challenge, of course,
is how to squeeze more voltage converter circuits into less space—without
sacrificing power or efficiency. Boost
converters, in particular, are becoming
more prevalent, as main supply voltages are lowered to accommodate core
logic circuits, while many components
require a higher supply voltage. The
LTC3426 boost converter meets the
challenge with converter-shrinking
features, including a low RDS(ON) monolithic switch, internal compensation
and a 3mm Г— 3mm Г— 1mm ThinSOT
package. The LTC3426 operates at
high frequency and therefore works
with small, low cost inductors and …
