2/3/4-Phase Controller for
CPU Applications
The NCP5392 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.
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.
