Description
The RC5058 is a synchronous mode DC-DC controller IC
which provides a highly accurate, programmable set of output
voltages for multi-voltage platforms such as the Intel Camino,
and provides a complete solution for the Intel Whitney and other
high-performance processors. The RC5058 features remote
voltage sensing, independently adjustable current limit, and a
proprietary Programmable Active Droop
transient response. The RC5058 uses a 5-bit D/A converter
to program the output voltage from 1.3V to 3.5V. The RC5058
uses a high level of integration to deliver load currents in excess
for optimal converter
