for VR10 and VR11 Pentium
IV Processor Applications
The NCP5388 is a twoï, threeï, or fourïphase buck controller
which combines differential voltage and current sensing, and
adaptive voltage positioning to power Intels most demanding
Pentium IV Processors and low voltage, high current power
supplies. Dualïedge pulseïwidth 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 capacitors to satisfy transient loadïline requirements.
A high performance operational error amplifier is provided, which
allows for easy compensation of the system. The proprietary method
of Dynamic Reference Injection makes the error amplifier
compensation virtually independent of the system response to VID
changes, eliminating the need for tradeoffs between load transients
and Dynamic VID performance.
