Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'PWPR' corresponds to the HTSSOP-16 package and tape-and-reel quantity when ordering. Confirm RoHS compliance status and moisture sensitivity level requirements prior to procurement. Ensure the supplier provides valid traceability documentation matching the manufacturer's part number specifications.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component for designs requiring a 5.5 A synchronous buck solution within a compact HTSSOP footprint. It is appropriate for applications needing a 650 kHz fixed frequency to minimize external passive size. Consider the D-CAP2 topology benefits for stability without compensation components.

Voltage Regulators - DC DC Switching Regulators Part Context

This part belongs to the TPS5452x family of synchronous step-down converters from Texas Instruments. It shares architectural similarities with the TPS54525 and TPS54528 but offers specific current ratings and Eco-mode enhancements. The PWPR suffix indicates the surface-mount HTSSOP packaging variant.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

The TPS54525 serves as a non-Eco-mode alternative within the same series. The TPS54528 offers similar functionality with potentially different current handling characteristics. Verify pin compatibility and thermal performance before substituting.
