ISL6506BCB

Power Supply Controllers, Monitors Overview

The ISL6506BCB 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 S3 and S5 digital control pins, utilizing an internal linear regulator for sleep states and external MOSFETs for active states.

Power Supply Controllers, Monitors Feature Summary

• Integrates control for 5VDUAL and 3.3VDUAL rails in ACPI designs
• Selectable operating mode via S3 and S5 digital control pins
• Internal linear regulator generates 3.3VDUAL during sleep states
• 2A current limit on the internal 3.3V LDO

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 distributors or official channels. Confirm RoHS compliance status as indicated in specific datasheets. Check manufacturing date codes against production timelines to ensure availability. Validate package markings match the 8-SOIC-EP specification. Ensure storage conditions respect humidity sensitivity requirements prior to assembly.

Power Supply Controllers, Monitors Selection Notes

Select this component for systems requiring integrated dual-rail control in ACPI environments. Choose the B variant over the A variant when a 2A current limit on the internal 3.3V LDO is required rather than 1A. Ensure the design accommodates the 8-lead narrow SOIC with exposed pad footprint. Verify compatibility with ATX power supply inputs for both active and sleep state transitions.

Power Supply Controllers, Monitors Part Context

This part belongs to the ISL6506B series, complementing other power building blocks like voltage regulators. It is functionally identical to the ISL6506A except for the sleep mode behavior of the 5VDUAL output and the internal LDO current limit specifications. The series targets standard temperature range applications in the PC industry.

Power Supply Controllers, Monitors Replacement Considerations

ISL6506ACB serves as a functional alternative with a 1A LDO current limit. ISL6506BCBZ-T offers the same electrical characteristics but in tape-and-reel packaging instead of tubes.
