The 300 mA integrated switch and 1 MHz switching frequency let you build a compact supply for bias rails, OLED panels, or small-signal high-voltage needs without an external FET. ## Input range and battery compatibility The 1.8 V minimum input covers a single-cell Li-ion battery from nearly full discharge (around 3.0 V) down to the protection cutoff. The 6 V maximum input also handles 2S alkaline or USB 5 V rails without a pre-regulator. For a 3.7 V Li-ion cell, the output can be set anywhere from 1.8 V to 28 V, making it suitable for generating a 12 V or 24 V bias rail from a single cell. ## Switch current and output power budget The 300 mA switch current limit sets the maximum output power. At 28 V output from a 3.3 V input, the achievable load current is roughly 60 mA, assuming 80 % efficiency. This is enough for small-signal bias rails, op-amp supplies, or OLED bias — not for high-current loads. The actual output current scales inversely with the output-to-input voltage ratio. ## Switching frequency and component size Switching at up to 1 MHz allows the use of small inductors (typically 4.7 µH to 22 µH) and ceramic capacitors, keeping the total solution footprint small. The 8-SON (3 mm × 3 mm) package itself is compact, and the high switching frequency means the external components also stay small — a good fit for space-constrained battery-powered designs.","metaTitle":"TPS61045ADRBR Step-Up Boost Converter, 28 V Output, 1 MHz","metaDescription":"Texas Instruments TPS61045ADRBR adjustable boost converter: 1.8 V to 6 V input, up to 28 V output, 300 mA switch, 1 MHz switching, -40°C to 85°C, 8-SON.","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)","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":"$0.8250","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/56e454ba3479d86ba68ed13f9c720000.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61045ADRBR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS61045ADRBR lead-free and RoHS compliant?","answer":"Texas Instruments typically marks RoHS compliance on the product label; the datasheet should confirm the specific environmental compliance status for this order code."},{"question":"Can TPS61045ADRBR be used for lithium-ion battery boost applications?","answer":"Yes.
