Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix 'RT' indicates the tape and reel packaging configuration when ordering. Confirm that the required output voltage does not exceed the maximum rated limit of 85V. Ensure thermal management strategies align with the WSON-6 package capabilities under expected load conditions. Cross-reference the exact part number with official Texas Instruments documentation to confirm availability and revision status.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this component when a high output voltage is required from a single-cell source. Evaluate the trade-off between switching frequency settings and inductor size. Consider the internal switch current limits relative to the target load. Verify compatibility with the desired control interface and enable pin logic levels for system integration.

Voltage Regulators - DC DC Switching Regulators Part Context

This device belongs to the TPS6139x family of boost converters designed for high-voltage output applications. It shares architectural similarities with other TI boost regulators but distinguishes itself through its extended output voltage capability. The family targets applications where standard boost converters cannot reach the necessary voltage levels without complex multi-stage solutions.

Voltage Regulators - DC DC Switching Regulators Replacement Considerations

Consult official cross-reference tools for parametrically similar parts. Verify that any substitute matches the 85V output capability and WSON-6 footprint. Ensure equivalent current handling and control features are present before substitution.
