NCP5382

2/3/4/5/6 Phase Buck

Controller for VR10 and

VR11 Pentium IV Processor

Applications

http://onsemi.com

The NCP5382 is a two−, three−, four−, five−, or six−phase buck

controller which combines differential voltage and current sensing,

and adaptive voltage positioning to power Intel’s most demanding

MARKING

DIAGRAM

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 capacitors to satisfy transient load−line 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.
