The output is fixed at 1.26 V, so no external feedback divider is needed — just the input and output caps and the inductor. ## Package and temperature — what the DSBGA means for assembly The part comes in a 6-bump DSBGA (6-XFBGA) package — 0.4 mm pitch, no leads, just solder balls on the bottom. This is a wafer-level chip-scale package; the die is essentially the package. That means the footprint is tiny, but the reflow profile needs to match the JEDEC standard for DSBGA, and the board must have a solder-mask-defined pad pattern. No underfill is required for most applications, but the small bump size means the PCB land should be non-solder-mask-defined (NSMD) for best reliability. The junction temperature limit is higher, but the 85°C ambient ceiling is the practical design-in number for the thermal budget. For a production BOM, this part does not force a qualification requalification cycle in the near term.","metaTitle":"TPS62674YFDR Buck Converter, 500 mA, 5.45 MHz, DSBGA-6","metaDescription":"Texas Instruments TPS62674YFDR step-down buck converter, fixed 1.26 V output, 500 mA, 5.45 MHz switching, 6-DSBGA package, -40 to 85°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"500mA","Number of Outputs":"1","Base Product Number":"TPS62674","Output Configuration":"Positive","Frequency - Switching":"5.45MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"4.8V","Voltage - Input (Min)":"2.3V","Voltage - Output (Max)":"-","Supplier Device Package":"6-DSBGA","Voltage - Output (Min/Fixed)":"1.26V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6270","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/1381f2f9608c9e9f43240a40dec587af.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62674YFDR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62674YFDR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62674YFDR when reusing this data.
