Description

The ISL6217 Multi-Phase Buck PWM control IC, with integrated half bridge gate drivers, provides a precision voltage regulation system for advanced Pentium“ IV microprocessors in notebook computers. Two-phase
operation eases the thermal management issues and load demand of Intel’s latest high performance processors. This control IC also features both input voltage feed-forward and average current mode control for excellent dynamic response, “Loss-less” current sensing using MOSFET RDS(ON) and user selectable switching frequencies from 250kHz to 1MHz per phase.

Features
• IMVP-IV™ and IMVP-IV+™ Compliant CORE Regulator
• Single and/or Two-phase Power Conversion
• “Loss-less” Current sensing for improved efficiency and reduced board area
− Optional Discrete Precision Current Sense Resistor
• Internal Gate-Drive and Boot-Strap Diodes
• Precision CORE Voltage Regulation
− 0.8% system accuracy over temperature
• 6-Bit Microprocessor Voltage Identification Input
• Programmable “Droop” and CORE Voltage Slew Rate to comply with IMVP-IV™ and IMVP-IV+™ specification
• Direct Interface with System Logic (STP_CPU# and DPRSLPVR) for Deep and Deeper Sleep modes of operation
• Easily Programmable voltage setpoints for Initial “Boot”, Deep Sleep and Deeper Sleep Modes
• Excellent Dynamic Response
− Combined Voltage Feed-Forward and Average Current Mode Control
• Overvoltage, Undervoltage and Overcurrent Protection
• Power-Good Output with internal blanking during VID and mode changes
• User programmable Switching Frequency of 250kHz - 1MHz per phase
• Pb-Free Plus Anneal Available (RoHS Compliant)
