NCP5389

2/3 Phase Buck Controller

for VR11 Pentium IV

Processor Applications

The NCP5389 is a two− or three−phase buck controller which

combines differential voltage and current sensing, and adaptive

MARKING

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

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.
