The 2.4 MHz switching frequency keeps the inductor small — a 2.2 µH or 3.3 µH shielded part is usually enough — and pushes the switching noise above the audio band. The package is a 14-VFDFN with an exposed thermal pad, listed as 14-VSON (4x3 mm). Under a hot-air station, preheat the board to 150 °C before hitting the pad — the exposed pad soaks heat fast, and without preheat you risk lifting the pad or cold-jointing the perimeter pins. If the design lives under the hood or in a downhole tool, you will need a wider-range part — this one stops at 85 °C.","metaTitle":"TPS63020DSJT Buck-Boost Regulator, 3.5A Switch, 2.4MHz","metaDescription":"Texas Instruments TPS63020DSJT buck-boost regulator, 1.8V-5.5V input, adjustable output up to 3.5A switch, 2.4MHz, -40°C to 85°C, 14-VSON.","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/Step-Down","Topology":"Buck-Boost","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"14-VFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3.5A (Switch)","Number of Outputs":"1","Base Product Number":"TPS63020","Output Configuration":"Positive","Frequency - Switching":"2.4MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"1.8V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"14-VSON (4x3)","Voltage - Output (Min/Fixed)":"1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.7400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ed08e9ee0387af320905f41c68eef045.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS63020DSJT/alternatives.json"},"ai":{"faq":[{"question":"Is the TPS63020DSJT suitable for a 5 V output from a single Li-ion cell?","answer":"Yes. The input range goes down to 1.8 V, so a single Li-ion cell (3.0–4.2 V) is well within the operating window. The adjustable output can be set to 5 V, and the buck-boost topology keeps the output regulated as the cell voltage drops below 5 V during discharge."},{"question":"What is the maximum output current of the TPS63020DSJT?","answer":"The internal switch is rated for 3.5 A. The actual continuous output current depends on the input-to-output voltage ratio — expect roughly 2 A at a 3.3 V output from a 3.6 V input."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS63020DSJT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS63020DSJT when reusing this data.
