ISL6333 Allgemeine Beschreibung

The ISL6333 three-phase PWM family of control ICs provide a precision voltage regulation system for advanced microprocessors. The integration of power MOSFET drivers into the controller IC marks a departure from the separate PWM controller and driver configuration of previous multi-phase product families. By reducing the number of external parts, this integration is optimized for a cost and space saving power management solution.Features• Intel VR11.1 Compatible- IMON Pin for Output Current Monitoring- Power State Indicator (PSI#) Pin for Phase Dropping and Higher Efficiency During Light Load States• CPURST_N Input to Eliminate Required ExtensiveExternal Circuit for proper PSI# Operation of Intel’sEaglelake Chipset Platform (ISL6333B, ISL6333C Only)• Integrated Multi-Phase Power Conversion- 3-Phase or 2-Phase Operation with Internal Drivers• Precision Core Voltage Regulation- Differential Remote Voltage Sensing- ±0.5% System Accuracy Over-Temperature- Adjustable Reference-Voltage Offset• Optimal Transient Response- Active Pulse Positioning (APP) Modulation- Adaptive Phase Alignment (APA)• Fully Differential, Continuous DCR Current Sensing- Integrated Programmable Current Sense Resistors- Accurate Load Line Programming- Precision Channel Current Balancing• Gate Voltage Optimization Technology (ISL6333,ISL6333B Only)• Power Saving Diode Emulation Mode (ISL6333, ISL6333B Only)• Optimized for use with Coupled Inductors• Variable Gate Drive Bias: +5V to +12V• Microprocessor Voltage Identification Inputs- 8-bit VID Input for Selecting VR11 DAC Voltages- Dynamic VID Technology• Dynamic VID Compensation• Overcurrent Protection and Channel Current Limit• Multi-tiered Overvoltage Protection• Digital Soft-Start• Selectable Operation Frequency up to 1.0MHz Per Phase• Pb-free (RoHS Compliant)
