2/3/4-Phase Controller for
CPU Applications
The NCP5392 provides up to a fourphase 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. Dualedge
pulsewidth modulation (PWM) combined with inductor current
sensing reduces system cost by providing the fastest initial response
to dynamic load events. Dualedge 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 closedloop transient response and Dynamic
VID performance.
