ISL6323A General Description

Monolithic Dual PWM Hybrid Controller Powering AMD SVI Split-Plane and PVI Uniplane ProcessorsThe ISL6323A dual PWM controller delivers high efficiency and tight regulation from two synchronous buck DC/DC converters. The ISL6323A supports hybrid power control of AMD processors which operate from either a 6-bit parallel VID interface (PVI) or a serial VID interface (SVI). The dual output ISL6323A features a multi-phase controller to support uniplane VDD core voltage and a single phase controller to power the Northbridge (VDDNB) in SVI mode. Only the multi-phase controller is active in PVI mode to support uniplane VDD only processors.Features• Processor Core Voltage Via Integrated Multi-Phase Power Conversion• Configuration Flexibility- 2-Phase Operation with Internal Drivers- 3- or 4-Phase Operation with External PWM Drivers• PSI_L Support with Phase Shedding for Improved Efficiency at Light Load• Serial VID Interface Inputs- Two Wire, Clock and Data, Bus- Conforms to AMD SVI Specifications• Parallel VID Interface Inputs- 6-bit VID input- 0.775V to 1.55V in 25mV Steps- 0.375V to 0.7625V in 12.5mV Steps• Precision Core Voltage Regulation- Differential Remote Voltage Sensing- ±0.6% System Accuracy Over-Temperature- Adjustable Reference-Voltage Offset• Optimal Processor Core Voltage Transient Response- Adaptive Phase Alignment (APA)- Active Pulse Positioning Modulation• Fully Differential, Continuous DCR Current Sensing- Accurate Load Line Programming- Precision Channel Current Balancing• Variable Gate Drive Bias: 5V to 12V• Overcurrent Protection• Multi-tiered Overvoltage Protection• Selectable Switching Frequency up to 1MHz• Simultaneous Digital Soft-Start of Both Outputs• Processor NorthBridge Voltage Via Single Phase Power Conversion• Precision Voltage Regulation- Differential Remote Voltage Sensing- ±0.6% System Accuracy Over Temperature• Serial VID Interface Inputs- Two Wire, Clock and Data, Bus- Conforms to AMD SVI Specifications• Overcurrent Protection• Continuous DCR Current Sensing• Variable Gate Drive Bias: 5V to 12V• Simultaneous Digital Soft-Start of Both Outputs• Selectable Switching Frequency up to 1MHz• Pb-Free Plus Anneal Available (RoHS Compliant)
