NCP5393B

2/3/4-Phase Controller for

CPU Applications

The NCP5393B 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 NCP5393B

incorporates differential voltage sensing, differential phase current

sensing, optional load−line voltage positioning, and programmable

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.

Reference Injection further simplifies loop compensation by

eliminating the need to compromise between response to load

transients and response to VID code changes.
