NCP5392Q

2/3/4-Phase Controller for

CPU Applications

The NCP5392Q provides up to a four−phase buck solution which

combines differential voltage sensing, differential phase current sensing,

and adaptive voltage positioning to provide accurately regulated power

for Intel processors. Dual−edge pulse−width modulation (PWM)

combined with inductor current sensing reduces system cost by

providing the fastest initial response to dynamic load events. Dual−edge

multiphase modulation reduces the total bulk and ceramic output

capacitance required to meet transient regulation specifications.

A high performance operational error amplifier is provided to

simplify compensation of the system. Dynamic Reference Injection

further simplifies loop compensation by eliminating the need to

compromise between closed−loop transient response and Dynamic

VID performance.

In addition, NCP5392Q provides an automatic power saving

feature (Auto−PSI). When Auto−PSI function is enabled, NCP5392Q

will automatically detect the VID transitions and direct the Vcore

regulator in or out of low power states. As a result, the best efficiency

scheme is always chosen.
