ISL6506BCBZA

Power Supply Controllers, Monitors Overview

The ISL6506BCBZA 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 pins, utilizing an internal linear regulator for 3.3VDUAL generation during sleep states or an external N-Channel MOSFET for active states. The ISL6506B variant provides a 2A current limit on its internal 3.3V LDO.

Power Supply Controllers, Monitors Feature Summary

• Integrates dual rail control for 5VDUAL and 3.3VDUAL outputs
• Supports ACPI-compliant design with selectable active and sleep modes
• Includes internal linear regulator for 3.3VDUAL voltage plane generation

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. Confirm RoHS compliance status as indicated in official datasheets. Ensure proper handling due to moisture sensitivity classification. Validate package dimensions against the SOIC-Narrow-8 specification prior to PCB integration.

Power Supply Controllers, Monitors Selection Notes

Select this model for systems requiring integrated control of dual voltage rails in ACPI environments. Choose the B suffix variant specifically when a 2A current limit on the internal 3.3V LDO is required, distinguishing it from the A variant which offers a 1A limit. Ensure compatibility with ATX power supply inputs for both active and sleep state operations.

Power Supply Controllers, Monitors Part Context

This component belongs to the ISL6506B series of power management ICs manufactured by Renesas Electronics Corporation. It serves as a specialized solution for managing CPU core voltages in legacy and modern PC architectures that adhere to Advanced Configuration and Power Interface standards.

Power Supply Controllers, Monitors Replacement Considerations

The ISL6506ACB is functionally identical except for the 1A LDO current limit. Verify if the higher 2A capacity of the B variant is necessary for the specific load requirements of the target motherboard design.
