NCP5395T

2/3/4-Phase Controller with

On Board Gate Drivers for

CPU Applications

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 (PSI) from CPU, and operates in a single

phase emulation diode mode to obtain a high efficiency at light load.

Dual−edge pulse−width modulation (PWM) 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.

MARKING DIAGRAM

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
