NCP5391
2/3 Phase Buck Controller
for VR11 Pentium IV
Processor Applications
The NCP5391 is a two- or three-phase buck controller which
combines differential voltage and current sensing, and adaptive
voltage positioning to power Intel's most demanding Pentium ? IV
Processors and low voltage, high current power supplies. Dual-edge
pulse-width modulation (PWM) combined with inductor current
sensing reduces system cost by providing the fastest initial response
to transient loads thereby requiring less bulk and ceramic output

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 the need for tradeoffs between load transients
