ISL6506CB

Power Supply Controllers, Monitors Overview

The ISL6506CB is a switching controller designed for ACPI-compliant power regulation in microprocessor and computer applications. It integrates control of the 5VDUAL and 3.3VDUAL rails within an 8-lead EPAD SOIC package. The device operates between 0°C and +70°C. It features selectable operating modes via digital control pins S3 and S5, utilizing an internal linear regulator for sleep states and external MOSFETs for active states to minimize losses.

Power Supply Controllers, Monitors Feature Summary

• Integrates control for 5VDUAL and 3.3VDUAL rails into a single compact package
• Supports ACPI-compliant designs with selectable active or sleep output modes
• Generates 3.3VDUAL voltage plane from ATX 5VSB during sleep states
• Utilizes external N-Channel pass MOSFETs for minimal loss in active states

Power Supply Controllers, Monitors Applications

• ACPI-compliant power regulation for motherboards
• Microprocessor power supply designs
• Computer application power management

Power Supply Controllers, Monitors Procurement Notes

Verify component authenticity through authorized Renesas or Intersil distributors. Confirm RoHS compliance status as historical data may vary. Check moisture sensitivity level handling requirements prior to assembly. Ensure the specific suffix matches the required thermal and electrical specifications for your design.

Power Supply Controllers, Monitors Selection Notes

Select this component for systems requiring integrated dual-rail control in ACPI environments. Compare ISL6506A and ISL6506B variants based on 5VDUAL shutdown behavior in deep sleep states. Verify compatibility with external MOSFET selection for optimal efficiency in active modes.

Power Supply Controllers, Monitors Part Context

Part of the ISL6506B series, complementing other power building blocks like voltage regulators. Designed specifically for microprocessor and computer applications requiring strict ACPI standards. Shares functional identity with ISL6506A except for specific sleep mode behaviors regarding the 5VDUAL output.

Power Supply Controllers, Monitors Replacement Considerations

ISL6506ACB and ISL6506BCB are functionally similar alternatives within the same family. Verify differences in 5VDUAL shutdown logic and internal LDO current limits before substitution.
