Overview
DATASHEET ISL6327A Enhanced 6-Phase PWM Controller with 8-Bit VID Code and Differential Inductor DCR or Resistor Current Sensing FN6833 Rev 0.
00 Feb 17, 2009 The ISL6327A controls microprocessor core voltage regulation by driving up to 6 synchronous-rectified buck channels in parallel.
Multiphase 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.
Microprocessor loads can generate load transients with extremely fast edge rates.
The ISL6327A utilizes Intersil’s proprietary Active Pulse Positioning (APP) and Adaptive Phase Alignment (APA) modulation scheme to achieve the extremely fast transient response with fewer output capacitors.
Today’s microprocessors require a tightly regulated output voltage position versus load current (droop).
The ISL6327A senses the output current con...
