The 2 MHz switching frequency lets the designer use a small, low-profile inductor — typically 1 µH or less — keeping the total power-stage footprint tight enough for space-constrained portable and battery-powered products. ## 0.5 V minimum input — deep-discharge battery operation With a minimum input voltage of 0.5 V, this part can start up and regulate from a single alkaline cell well into its discharge curve, or from a Li-ion cell that has dropped below its typical UVLO threshold. The adjustable output range from 1.8 V up to 4 V covers the rails for 1.8 V logic, 2.5 V I/O, 3.3 V sensor supplies, and 4 V LED bias.","metaTitle":"TI TPS61021ADSGT Boost Converter, 3A Switch, 2MHz, 8-WSON","metaDescription":"Texas Instruments TPS61021ADSGT step-up boost converter with 3A switch, 2MHz switching, 0.5V min input, synchronous rectification, -40 to 125°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-Up","Topology":"Boost","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A (Switch)","Number of Outputs":"1","Base Product Number":"TPS61021","Output Configuration":"Positive","Frequency - Switching":"2MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"4.4V","Voltage - Input (Min)":"0.5V","Voltage - Output (Max)":"4V","Supplier Device Package":"8-WSON (2x2)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d0d9f5a482d2d3468b4bbb59462e1a37.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61021ADSGT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS61021ADSGT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS61021ADSGT when reusing this data.
