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. Features
