General Description
The AT1391 provides complete control and
protection for a DC/DC converter optimized for
high-performance microprocessor applications. It
is designed to drive one P-Channel in a buck
topology. The AT1391 integrates all of the control,
output adjustment, 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 AT1391 is a family of low-noise
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
