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.
