ISL6568 General Description

Two-Phase Buck PWM Controller with Integrated MOSFET Drivers for VRM9, VRM10, and AMD Hammer ApplicationsThe ISL6568 two-phase PWM control IC provides 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• Integrated Multi-Phase Power Conversion - 1 or 2-Phase Operation• Precision Core Voltage Regulation - Differential Remote Voltage Sensing - ±0.5% System Accuracy Over Temperature - Adjustable Reference-Voltage Offset• Precision Channel Current Sharing - Uses Loss-Less rDS(ON) Current Sampling• Accurate Load Line Programming - Uses Loss-Less Inductor DCR Current Sampling• Variable Gate Drive Bias: 5V to 12V• Microprocessor Voltage Identification Inputs - Up to a 6-Bit DAC - Selectable between Intel’s VRM9, VRM10, or AMD Hammer DAC codes - Dynamic VID-on-the-fly Technology• Overcurrent Protection• Multi-tiered Overvoltage Protection• Digital Soft-Start• Selectable Operation Frequency up to 1.5MHz Per Phase• Pb-Free Plus Anneal Available (RoHS Compliant)
