Special Purpose Regulators Procurement Notes

Verify the specific suffix 'T' indicates tape and reel packaging configuration distinct from bulk units. Confirm current manufacturing status as Intersil assets are managed by Renesas. Ensure compatibility with existing PCB footprints for the 40-QFN package before procurement.

Special Purpose Regulators Selection Notes

Select this component for applications requiring a single-phase solution for mobile processors adhering to IMVP-6 standards. Consider the thermal performance of the QFN package and the operating temperature range relative to the system environment. Verify that the required switching frequency falls within the supported 200kHz to 600kHz range.

Special Purpose Regulators Part Context

This part belongs to the ISL6261A series of single-phase core regulators. It is part of the broader portfolio of power management ICs developed for mobile computing platforms. The product line focuses on providing efficient voltage regulation for high-performance microprocessors.

Special Purpose Regulators Replacement Considerations

Check for direct pin-to-pin replacements within the ISL6261 family or newer generations such as the ISL6269 series if multi-phase requirements arise. Verify electrical parameter compatibility and software register settings when substituting with other single-phase controllers.
