For a 350 mA rail, the inductor footprint is roughly 2.0 × 1.6 mm — the whole converter fits in a corner of the board that a slower 2 MHz part would need twice the area for. Input voltage floor is 2.3 V, ceiling 5.5 V — covers a single-cell Li-ion through its full discharge curve and a regulated 5 V bus. The output is fixed at 1.8 V, no external divider needed. The synchronous rectifier is integrated, so the BOM omits the usual Schottky catch diode. That covers outdoor telecom cabinets, factory-floor sensors, and automotive cabin modules. Not rated for under-hood or downhole — those need the 125°C or 150°C grades found in the automotive AEC-Q100 siblings. ## Package — 6-DSBGA, 0.5 mm pitch Supplied in a 6-bump DSBGA (6-XFBGA) package, 0.5 mm pitch. ## Lifecycle — active production, ROHS3 compliant The base product number is TPS62619; the YFDT suffix identifies the 6-DSBGA package and tape-and-reel delivery.","metaTitle":"TPS62619YFDT – TI 6 MHz 350 mA Buck Regulator, 6-DSBGA","metaDescription":"Texas Instruments TPS62619YFDT step-down converter: 2.3 V–5.5 V input, 1.8 V fixed output, 350 mA, 6 MHz switching, synchronous rectifier, -40°C to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-XFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"350mA","Number of Outputs":"1","Base Product Number":"TPS62619","Output Configuration":"Positive","Frequency - Switching":"6MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.3V","Voltage - Output (Max)":"-","Supplier Device Package":"6-DSBGA","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5800","priceTiers":[{"qty":1,"price":"$1.58000","currency":"USD"},{"qty":10,"price":"$1.41300","currency":"USD"},{"qty":25,"price":"$1.34160","currency":"USD"},{"qty":100,"price":"$1.10200","currency":"USD"},{"qty":250,"price":"$1.03012","currency":"USD"},{"qty":500,"price":"$0.91032","currency":"USD"},{"qty":1250,"price":"$0.71868","currency":"USD"},{"qty":2500,"price":"$0.67800","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/314c91d247fa0e45957c762cf8693650.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62619YFDT/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy TPS62619YFDT?","answer":"The TPS62619YFDT is an active Texas Instruments part.
