The 900 mA switch current limit sets the maximum output current — at 3.3 V out from a 3.0 V input, expect roughly 600 mA continuous before the switch hits its limit; from a 5 V input the headroom is higher. ## 2.4 MHz switching — inductor shrinks, but layout discipline matters The 2.4 MHz switching frequency lets the designer use a small 1 µH to 2.2 µH inductor, saving board area in space-constrained designs. The trade-off: the fast edges demand a tight layout — the input capacitor and inductor loop must stay under 5 mm trace length to keep switching noise off the output. The synchronous rectifier (integrated low-side FET) eliminates the external Schottky diode, reducing BOM count and improving efficiency at light loads. That means no last-time-buy deadline and no forced redesign for the foreseeable production horizon.","metaTitle":"TPS63031DSKT Buck-Boost Regulator, 2.4 MHz, 900 mA Switch","metaDescription":"Texas Instruments TPS63031DSKT step-up/step-down regulator, fixed 3.3 V output, 1.8 V to 5.5 V input, 900 mA switch, 2.4 MHz, -40°C to 85°C, 10-WFDFN.","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":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-WFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"900mA (Switch)","Number of Outputs":"1","Base Product Number":"TPS63031","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)":"-","Supplier Device Package":"10-SON (2.5x2.5)","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/82ed8d9bf302f79eaee68e86b3ffa23a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS63031DSKT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS63031DSKT a replacement for TPS63030?","answer":"The TPS63031DSKT is a fixed 3.3 V output variant in the same TPS6303x family. The TPS63030 is the adjustable-output version. They are pin-compatible — the feedback pin differs — so a board designed for the adjustable part can use the TPS63031DSKT only if the output voltage requirement is exactly 3.3 V and the feedback network is removed or adjusted."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS63031DSKT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS63031DSKT when reusing this data.
