DESCRIPTION
The LC3406 is a high-efficiency, DC-to-DC stepdown
switching regulators, capable of delivering up
to 1.2A of output current. The device operates from
an input voltage range of 2.6V to 7.0V and provides
an output voltage from 0.6V to VIN, making the
LC3406 ideal for low voltage power conversions.
Running at a fixed frequency of 1.5MHz allows the
use of small external components, such as ceramic
input and output caps, as well as small inductors,
while still providing low output ripples. This low
noise output along with its excellent efficiency
achieved by the internal synchronous rectifier,
making LC3406 an ideal green replacement for large
power consuming linear regulators. Internal softstart
control circuitry reduces inrush current. Shortcircuit
and thermal-overload protection improves
design reliability.
