NCP5392P

2/3/4-Phase Controller for

CPU Applications

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.

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.

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.
