It switches at 2.25 MHz. ## Package and rework — 6-WSON with exposed pad Without it, the part runs hotter than the 1A rating suggests at elevated ambient. Orientation is straightforward: the WSON package has a pin-1 chamfer on the top, and the datasheet layout shows the pad connection. A hot-air rework station can lift this part cleanly if the board has enough copper soak to prevent pad lifting. The synchronous rectifier (integrated low-side FET) improves efficiency at light loads, which matters for always-on industrial applications where every milliwatt counts.","metaTitle":"TI TPS62291DRVT Step-Down Buck Regulator, 3.3V Fixed Output","metaDescription":"Texas Instruments TPS62291DRVT step-down buck converter, 2.3V to 6V input, fixed 3.3V output at 1A. 2.25 MHz switching, 6-WSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Function":"Step-Down","Topology":"Buck","Packaging":"Tape & Reel (TR) Cut Tape (CT)","Output Type":"Fixed","Part Status":"Active","Mounting Type":"Surface Mount","Package / Case":"6-WDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"1A","Number of Outputs":"1","Base Product Number":"TPS62291","Output Configuration":"Positive","Frequency - Switching":"2.25MHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.3V","Voltage - Output (Max)":"-","Supplier Device Package":"6-WSON (2x2)","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/78ff04423e21c6a41637bd0cf821d115.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62291DRVT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62291DRVT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62291DRVT when reusing this data.
