Five pins, surface-mount, with a small footprint that fits into compact automotive PCBs. This covers automotive under-hood and engine-bay environments, as well as industrial applications where the ambient temperature can push past 85°C. The 125°C ceiling is the junction temperature limit for the internal switch — derate the 400 mA output current above 85°C ambient per the datasheet thermal curves. ## Sourcing reality — Last Buy channel We source it through independent and surplus channels against an RFQ. If you need a production-volume commitment, this is the time to place the order — once the last-time-buy window closes, the surplus channel is the only option.","metaTitle":"TPS61040AQDBVRQ1 Automotive Boost Regulator, 28V, Last Buy","metaDescription":"Texas Instruments TPS61040AQDBVRQ1 is an automotive-grade step-up DC-DC regulator. 1.8V to 6V input, 28V output, 400 mA, AEC-Q100.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Last Buy","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Type":"DC DC Regulator","Grade":"Automotive","Series":"-","Dimming":"No","Package":"Tape & Reel (TR) Cut Tape (CT)","Topology":"Step-Up (Boost)","Frequency":"1MHz","Applications":"-","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Package / Case":"SC-74A, SOT-753","Product Status":"Last Time Buy","lifecycle_stage":"eol_hot","Voltage - Output":"28V","Number of Outputs":"1","Internal Switch(s)":"Yes","Operating Temperature":"-40°C ~ 125°C (TA)","Voltage - Supply (Max)":"6V","Voltage - Supply (Min)":"1.8V","Supplier Device Package":"SOT-23-5","Current - Output / Channel":"400mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.4000","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/c72bd6044a8e3ffbc93cb212a417f558.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61040AQDBVRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS61040AQDBVRQ1 AEC-Q100 qualified?","answer":"Yes, the TPS61040AQDBVRQ1 is AEC-Q100 qualified, which is the automotive stress-test qualification for integrated circuits.
