NCP5395T: 2/3/4-Phase Controller with Gate Drivers

The NCP5395T 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 both Intel and AMD processors. It also receives power saving command from CPU, and operates in a single phase emulation diode mode to obtain a high efficiency at lightload. Dual edge pulse width modulation combined with precise inductor current sensing provides the fastest initial response to dynamic load events both in power saving and normal modes. Dual edge multiphase modulation reduces the total bulk and ceramic output capacitance required therefore reducing the system cost 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.
