ISL6326 General Description

4-Phase PWM Controller with 8-Bit DAC Code Capable of Precision DCR Differential Current SensingThe 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.Features• Proprietary Active Pulse Positioning and Adaptive Phase Alignment Modulation Scheme• Precision Multiphase Core Voltage Regulation - Differential Remote Voltage Sensing - ±0.5% System Accuracy Over Life, Load, Line and Temperature - Adjustable Precision Reference-Voltage Offset• Precision Resistor or DCR Current Sensing - Accurate Load-Line Programming - Accurate Channel-Current Balancing - Differential Current Sense• Microprocessor Voltage Identification Input - Dynamic VID™ Technology - 8-Bit VID Input with Selectable VR11 Code and Extended VR10 Code at 6.25mV Per Bit• Thermal Monitoring• Integrated Programmable Temperature Compensation• Overcurrent Protection and Channel Current Limit• Overvoltage Protection• 2-, 3- or 4-Phase Operation• Adjustable Switching Frequency up to 1MHz Per Phase• Package Option - QFN Compliant to JEDEC PUB95 MO-220 QFN - Quad Flat No Leads - Product Outline - QFN Near Chip Scale Package Footprint; Improves PCB Efficiency, Thinner in Profile• Pb-Free (RoHS Compliant)
