DC DC Switching Controllers Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance when sourcing. Confirm the package variant matches the required PCB footprint. Ensure the supplier provides valid traceability documentation. Check that the component meets the specified operating temperature range for the intended environment. Validate the datasheet revision against the manufacturing date code.

DC DC Switching Controllers Selection Notes

Select this controller when space constraints require a small SOT-23-6 package. Choose this part for designs needing a fixed 450 kHz switching frequency. Consider this IC for low-power applications where 20 uA quiescent current is critical. Ensure the external MOSFET selection aligns with the 3 A output current requirement. Verify input voltage stability within the 1.8 V to 6.5 V range.

DC DC Switching Controllers Part Context

This component belongs to the TPS6420x family of step-down controllers. It shares functional similarities with other members like the TPS64200 and TPS64202. The family is designed for general-purpose DC-DC conversion. Common variants differ in pinout or specific feature sets. This model represents a standard configuration within the series.

DC DC Switching Controllers Replacement Considerations

The TPS64201DBVT is a tape-and-reel alternative to the DBVR reel variant. Direct pin-compatible substitutes may include other TI buck controllers in similar packages. Verify electrical parameters before substituting with non-TI components.
