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.
