General Description
The AT1368 provides complete control and
protection for a DC/DC converter optimized for
high-performance microprocessor applications. It
is designed to drive one P-Channel and one N-
Channel MOSFETs in a synchronous-rectified
buck topology. The AT1368 integrates all of the
control, output adjustment, monitoring and
protection functions into a single package. The
output voltage of the converter can be precisely
regulated with a maximum tolerance of
±
2% over
temperature and line voltage variations. The
AT1368 is a family of low-noise synchronous step-
down DC/DC converters that is ideally suited for
systems powered from a 1-cell Li-ion battery or
from a 3-cell to 4-cell NiCd, NiMH, or alkaline
battery. It can also be used to USB-Based power
system.
