The single output is positive and adjustable — no synchronous rectifier, so the external Schottky diode selection matters for efficiency. The input range is 1.8V to 6V, with a single adjustable output up to 28V. The 300 mA switch current limits the output power. At 28V output from 3.3V input, the maximum output current is roughly 300 mA × (3.3V / 28V) × efficiency — expect about 30 mA to 35 mA usable. If your load needs more, look at a boost with a higher switch rating or external FET. ## Package and thermal handling for the rework bench The TPS61045DRBR comes in an 8-VDFN exposed pad package (3x3 mm SON).","metaTitle":"TPS61045DRBR Step-Up Regulator, 1.8V–28V Output, Active","metaDescription":"Texas Instruments TPS61045DRBR boost regulator: 1.8V to 6V input, adjustable output to 28V, 300 mA switch, 1 MHz switching, -40°C to 85°C, 8-SON (3x3 mm).","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-Up","Topology":"Boost","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-VDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"300mA (Switch)","Number of Outputs":"1","Base Product Number":"TPS61045","Output Configuration":"Positive","Frequency - Switching":"Up to 1MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"1.8V","Voltage - Output (Max)":"28V","Supplier Device Package":"8-SON (3x3)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/56e454ba3479d86ba68ed13f9c720000.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61045DRBR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61045DRBR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61045DRBR when reusing this data.
