DATASHEET ISL6326 4-Phase PWM Controller with 8-Bit DAC Code Capable of Precision DCR Differential Current Sensing FN9262 Rev 1.00 May 5, 2008 The ISL6326 controls microprocessor core voltage regulation by driving up to 4 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 dis.

DATASHEET ISL6326 4-Phase PWM Controller with 8-Bit DAC Code Capable of Precision DCR Differential Current Sensing FN9262 Rev 1.00 May 5, 2008 The ISL6326 controls microprocessor core voltage regulation by driving up to 4 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 ISL6326 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 ISL6326 senses the output current continuously by utili.
