That means it can keep a 3.3V rail alive from a single alkaline cell that's nearly dead — handy for portable gear where you want every last drop of battery life. The 1.6A switch rating gives you headroom for loads up to around 400-500 mA continuous, depending on input voltage and inductor choice. ## SOT-23-5 footprint and thermal reality The TPS613221ADBVR comes in a SOT-23-5 package. That's a five-pin part with a small footprint — good for tight layouts, but the thermal dissipation is limited. The switching frequency range of 500 kHz to 2 MHz lets you trade off inductor size against efficiency — 1 MHz is a common sweet spot for a compact design. ## Active production, no LTB worry For a BOM line, this is a straightforward sourcing decision — no last-time-buy math, no broker scavenger hunt.","metaTitle":"TPS613221ADBVR Boost Converter, 3.3V Fixed Output","metaDescription":"Texas Instruments TPS613221ADBVR step-up DC-DC converter, fixed 3.3V output, 1.6A switch, 0.9V-5.5V input, SOT-23-5, active production.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Up","Topology":"Boost","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SC-74A, SOT-753","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"1.6A (Switch)","Number of Outputs":"1","Base Product Number":"TPS613221","Output Configuration":"Positive","Frequency - Switching":"500kHz ~ 2MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"0.9V","Voltage - Output (Max)":"-","Supplier Device Package":"SOT-23-5","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/fc46c677e35112264ba7f5efad4d7fc5.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS613221ADBVR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS613221ADBVR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS613221ADBVR when reusing this data.
