ISL6314 pdf datasheet (Single-

The ISL6314 single-phase PWM control IC provides a
precision voltage regulation system for advanced
microprocessors. This controller IC maintains the same
features as the multi-phase product family, but reduces the
output to a single-phase, for lower current systems. By
reducing the number of external parts, this integration is
optimized for a cost and space saving power management
solution.
One outstanding feature of this controller IC is its multiprocessor
compatibility, allowing it to work with both Intel and
AMD microprocessors. Included are programmable VID
codes for Intel VR11 as well as AMD 5-bit and 6-bit DAC
tables. A circuit is provided for remote voltage sensing,
compensating for any potential difference between remote
and local grounds. The output voltage can also be positively
or negatively offset through the use of a single external
resistor.
