Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix DRLR against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and pinout compatibility. Ensure that the sourcing channel provides documentation confirming RoHS compliance and material declarations. Cross-reference the part number with the latest Texas Instruments release notes to validate manufacturing status and any potential design changes.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a compact solution is required for stepping down 2.7 V to 6 V inputs to lower logic or analog supply rails. The fixed 2.25 MHz frequency is suitable for applications prioritizing board area over ultra-low noise requirements. Compare performance metrics against the broader TPS62850x family if higher current capacity or automotive qualification is needed for the target environment.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the TPS62850x series of synchronous buck converters from Texas Instruments. The series offers multiple current ratings and configurations within the same footprint family. The TPS628501 specifically denotes the 1-A variant with a fixed switching frequency, distinguishing it from adjustable frequency or higher-current counterparts in the lineup.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult the TPS62850x family datasheet for direct functional substitutes such as TPS628502 or TPS628503 if higher current is required. Verify pin-to-pin compatibility and thermal characteristics before substituting with other Texas Instruments buck converters.
