NCP5392Q中文资料2/3/4-Phase VR11.1 Buck Controller数据手册ONSEMI规格书

描述 Description

The NCP5392Q provides up to a 4-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 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 amplifer 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.
