Procurement Notes

Verify the complete part number including suffixes like AEC1-Z against official MPS documentation to ensure correct automotive qualification and package type. Confirm pinout compatibility with your PCB layout before ordering. Check for any recent revisions or obsolescence notices directly from Monolithic Power Systems to avoid sourcing discontinued variants.

Selection Notes

Select this component when dual isolated outputs are required from a single high-voltage automotive rail. Ensure the input voltage does not exceed 60 V and that thermal management meets the 3 A per channel requirement. Verify that the fixed 500 kHz frequency aligns with EMI constraints and inductor selection guidelines provided in the datasheet.

Part Context

This device belongs to the MPQ4272 family of dual-channel synchronous buck converters. It is specifically engineered for harsh automotive environments, offering high integration and reliability. The GVE package indicates a specific leaded footprint suitable for through-hole or surface-mount assembly depending on the exact variant details found in the mechanical drawings.

Replacement Considerations

Check MPS official cross-reference lists for direct replacements. Consider MPQ4272 variants with different suffixes for minor packaging or temperature grade differences. Avoid non-MPS alternatives unless fully validated against electrical and thermal specifications.
