Power Management - Specialized Procurement Notes

Verify the specific package variant (8-TSSOP or 8-MSOP) required for your PCB layout, as both are listed under this part number. Confirm RoHS compliance status with the supplier, as sources indicate potential non-compliance for certain revisions. Ensure the manufacturer source is recognized, noting Fairchild's acquisition by ON Semiconductor, to guarantee component authenticity and traceability.

Power Management - Specialized Selection Notes

Select this component when designing circuits powered by two-series cells requiring regulated higher voltages. Its low 85µA supply current makes it suitable for always-on battery applications. Consider the 95% efficiency at 200mA load for thermal management. Verify input voltage compatibility with the 1.6V minimum specification before integration into the system design.

Power Management - Specialized Part Context

This part belongs to the ML4854 series of power management ICs from Fairchild Semiconductor. It functions specifically as a DC-DC boost converter optimized for portable applications. The IT suffix typically denotes temperature rating and packaging details within the manufacturer's coding scheme, distinguishing it from other variants in the same functional family.

Power Management - Specialized Replacement Considerations

Check for direct pin-compatible alternatives from ON Semiconductor following the Fairchild acquisition. Verify if newer revisions offer updated RoHS compliance while maintaining identical electrical characteristics and package dimensions for seamless board replacement.
