DATASHEET

Rev 3.00

December 29, 2004

Optimized Multiphase PWM Controller with 6-Bit DAC for VR10.X Application

The ISL6556A controls microprocessor core voltage

regulation by driving up to 4 synchronous-rectified buck

channels in parallel. Multi-phase buck converter architecture

uses interleaved timing to multiply channel ripple frequency

and reduce input and output ripple currents. Lower ripple

results in fewer components, lower component cost, reduced

power dissipation, and smaller implementation area.

The ISL6556A utilizes r

DS(ON)

current sensing in each

phase for adaptive voltage positioning (droop), channel-

current balancing, and overcurrent protection. To ensure

droop accuracy, an external NTC compensation circuit can

be used to completely nullify the effect of temperature

related variation in r

DS(ON)

A unity gain, differential amplifier is provided for remote

voltage sensing. Any potential difference between remote

and local grounds can be eliminated using the remote-sense

amplifier. The precision threshold-sensitive enable input is

available to accurately coordinate the start up of the

ISL6556A with Intersil MOSFET driver IC. Dynamic-VID™

technology allows seamless on-the-fly VID changes. The

offset pin allows accurate voltage offset settings that are

independent of VID setting. The ISL6556A uses 5V bias and

has a built-in shunt regulator to allow 12V bias using only a

small external limiting resistor.
