NCP5395 Product Preview 2/3/4-Phase Controller with On Board Gate Drivers for CPU Applications  The NCP5395 provides up to a four–phase buck solution which combines differential voltage sensing, differential phase current sensing, adaptive voltage positioning, and on board gate drivers. 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. The on board gate drivers includes adaptive non overlap and power saving operation. A high performance operational error amplifier is provided to simplify compensation of the system. Patented Dynamic Reference Injection further simplifies loop compensation by eliminating the need to compromise between closed–loop transient response and Dynamic VID performance.
