NCP5392P

2/3/4-Phase Controller for

CPU Applications

The NCP5392P 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 both Intel and AMD 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.

MARKING

DIAGRAM

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, NCP5392P provides an automatic power saving

feature (Auto-PSI). When Auto-PSI function is enabled, NCP5392P

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.
