Procurement Notes

Verify the complete part number including suffixes such as 'P' which may indicate tape-and-reel packaging or specific temperature grades. Confirm RoHS compliance status through official datasheets. Ensure compatibility with your PCB footprint by checking the package dimensions in the mechanical drawings provided by MPS.

Selection Notes

Select this component when a compact solution is required for converting higher voltages to lower logic or analog levels. Consider the maximum load current requirements and ensure the thermal performance meets your enclosure constraints. Evaluate the desired switching frequency against EMI requirements and inductor size limitations.

Part Context

This part belongs to the MP26xx family of synchronous buck converters designed for medium-power applications. It shares architectural similarities with other members but offers specific electrical characteristics tailored for industrial and telecom environments. The AGR package denotes an 8-lead TSSOP form factor suitable for space-constrained designs.

Replacement Considerations

Direct replacements within the same family include parts like the MP2636 or MP2637, depending on current and voltage requirements. Verify pin-to-pin compatibility and electrical specifications before substitution. Cross-reference with competitors only if functional equivalence is confirmed via detailed parameter comparison.
