POWER MANAGEMENT
Description
The SC1408 is a low voltage boost controller that
operates from a 1.8V to 16.5V input range. The SC1408
was designed for two cell Alkaline or single cell Lithium
Ion
battery
applications.
external components it can be used as a boost converter
or a buck/boost converter. A Shutdown pin allows the
user to turn the controller off, reducing supply current to
less than 2μA typical. Output voltage can be preset to 5V
or is adjustable from 3V to 16.5V with a resistor divider.
The controller changes frequency in light load conditions
to improve efficiency.
