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.

CASE 485K

PLASTIC

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
