ISL6568IR

Special Purpose Regulators Overview

The ISL6568IR is a two-phase PWM control IC designed for precision voltage regulation of advanced microprocessors. It integrates power MOSFET drivers and supports dynamic phase shedding and adaptive voltage positioning (AVP) to meet Intel VRM10 load-line requirements. The device operates with an input voltage range of 3V to 12V and provides an adjustable output voltage from 0.84V to 1.6V. It is housed in a 32-QFN (5x5 mm) package with an exposed pad, suitable for surface mount installation.

Special Purpose Regulators Feature Summary

• Integrates power MOSFET drivers within the controller IC
• Supports dynamic phase shedding for efficiency optimization
• Features adaptive voltage positioning (AVP)
• Complies with Intel VRM10 load-line specifications

Special Purpose Regulators Applications

• Intel VRM9 applications
• Intel VRM10 applications
• AMD Hammer applications

Special Purpose Regulators Procurement Notes

Verify component status as the ISL6568IR is listed as obsolete or discontinued by the manufacturer. Confirm RoHS compliance status, as sources indicate non-compliance for this specific suffix. Ensure availability of replacement components or alternative packages if current stock is limited. Check for any product change notices regarding packaging or labeling updates that may affect integration.

Special Purpose Regulators Selection Notes

Select this component for designs requiring integrated two-phase control with driver capabilities. It is appropriate for systems needing AVP and phase shedding to satisfy strict VRM10 load-line tolerances. Consider the 32-QFN package constraints and thermal dissipation requirements via the exposed pad. Verify compatibility with target processor VID codes and input voltage ranges before finalizing the design.

Special Purpose Regulators Part Context

The ISL6568 belongs to Renesas' family of special purpose regulators for microprocessor voltage regulation. It serves as a successor or companion to earlier models like the ISL6566 and ISL6560, offering enhanced integration by combining PWM control with gate drivers. This consolidation reduces component count and board space compared to discrete solutions.
