DescriptionThe RC5054A provides complete control and protection for
a DC-DC converter optimized for high-performance micro-
processor applications. It is designed to drive two N-Channel
MOSFETs in a synchronous-rectified buck topology. The
RC5054A integrates all of the control, output adjustment,
monitoring and protection functions into a single package.
The output voltage of the converter is easily adjusted and
precisely regulated. The RC5054A includes a 5-input digital-
to-analog converter (DAC) that adjusts the output voltage
from 2.1V
to 3.5V
in 0.1V increments and from
1.3V
to 2.1V
in 0.05V steps.
The RC5054A provides simple, single feedback loop, volt-
