Overview
NCP5392Q 2/3/4- Phase Controller for CPU Applications The NCP5392Q 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.
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.
In addition, NCP5392Q provides an automatic power saving feature (Auto- PSI).
When Auto- PSI function is enabled, NCP5392Q will automatic...
