NCP5387
2/3/4 Phase Controller for
CPU Applications
The NCP5387 is a two−, three−, or four−phase buck controller
which combines differential voltage and current sensing, and
adaptive voltage positioning to power both AMD and Intel
processors. Dual−edge pulse−width modulation (PWM) combined
with inductor current sensing reduces system cost by providing the
fastest initial response to transient load events. Dual−edge
multi−phase modulation reduces total bulk and ceramic output
capacitance required to satisfy transient load−line regulation.
A high performance operational error amplifier is provided, which
allows easy compensation of the system. The proprietary method of
Dynamic Reference Injection (Patented) makes the error amplifier
compensation virtually independent of the system response to VID
changes, eliminating tradeoffs between overshoot and dynamic VID
performance.
