Description
The RC5061 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 RC5061 features remote
voltage sensing, independently adjustable current limit, and
Active Droop for optimal converter transient response. The
RC5061 uses a 5-bit D/A converter to program the output
voltage from 1.3V to 3.5V. The RC5061 uses a high level of
integration to deliver load currents in excess of 16A from a 5V
