Product Preview
2/3/4-Phase Controller with
On Board Gate Drivers for
Down ? bonded to
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 V ID performance.
