Overview
NCP5392T 2/3/4-Phase Controller with Light Load Power Saving Enhancement for CPU Applications The NCP5392T 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 Intel processors.
It also receives power saving command (PSI) from CPU, and operates in a single phase emulation diode mode to obtain a high efficiency at light load.
Dual−edge pulse−width modulation (PWM) combined with precise inductor current sensing provides the fastest initial response to dynamic load events both in power saving and normal modes.
Dual−edge multiphase modulation reduces the total bulk and ceramic output capacitance required therefore reducing the system cost 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 ...
