NCP5392Q

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 automatically detect the VID transitions and direct the Vcore regulator in or out of low power states. As a result, the best efficiency scheme is always chosen.
