NCP5382
2/3/4/5/6 Phase Buck
Controller for VR10 and
VR11 Pentium IV Processor
Applications
The NCP5382 is a two, three, four, five, or sixphase 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. Dualedge pulsewidth 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 loadline requirements.
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 the need for tradeoffs between load transients
and Dynamic VID performance.
