2/3/4-Phase Controller for
CPU Applications
The NCP6251 is a multiphase synchronous buck regulator
controller designed to power the Core and Northbridge of an AMD
microprocessor. The controller has a user configurable two, three, or
four phase regulator for the Core and an independent single phase
regulator to power the microprocessor Northbridge. The NCP6251

incorporates differential voltage sensing, differential phase current
sensing, optional load ? line voltage positioning, and programmable
V DD and V DDNB offsets to provide accurately regulated power
parallel ? and serial ? VID AMD processors. Dual ? edge multiphase

modulation provides the fastest initial response to dynamic load
events. This reduces system cost by requiring less bulk and ceramic
output capacitance to meet transient regulation specifications.
High performance operational error amplifiers are provided to
simplify compensation of the V DD and V DDNB regulators. Dynamic
Reference Injection further simplifies loop compensation by
eliminating the need to compromise between response to load
transients and response to VID code changes.
