It takes a 2.7 V to 10 V input rail and delivers an adjustable output from 0.7 V up to 6 V — covering everything from a 1.2 V FPGA core to a 5 V sensor supply. The 850 kHz fixed switching frequency keeps the external inductor small — typically a 4.7 µH or 10 µH part — which is the whole point of this regulator: you trade a little efficiency at very light loads for a compact, low-BOM-count power stage. The synchronous rectifier is integrated, so there is no external Schottky diode to place or fail. On a repair bench, when a board with this regulator goes dead, the scorch mark is usually on the input cap or the inductor, not the IC itself — the TPS62051 is a tough part. ## Output voltage range and thermal envelope The output adjusts from a 0.7 V minimum up to 6 V maximum, set by a resistor divider on the FB pin. That 0.7 V floor is low enough to power modern 0.9 V or 1.0 V core rails on DSPs or FPGAs, while the 6 V ceiling handles legacy 5 V logic or analog supplies. The 125°C ceiling is the junction limit, so ambient temperature plus self-heating from the 800 mA load must stay under that number. No official successor has been designated, which means the base TPS62051 die is the current design-in target.","metaTitle":"TPS62051DGSRG4 Step-Down Regulator, 800 mA, 10-VSSOP","metaDescription":"Texas Instruments TPS62051DGSRG4 buck converter: 2.7–10 V input, adjustable 0.7–6 V output, 800 mA, 850 kHz, -40 to 125 °C.","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)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","lifecycle_stage":"eol_hot","Current - Output":"800mA","Number of Outputs":"1","Base Product Number":"TPS62051","Output Configuration":"Positive","Frequency - Switching":"850kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"10V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"6V","Supplier Device Package":"10-VSSOP","Voltage - Output (Min/Fixed)":"0.7V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9504","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/974689d31af561ba45fb5571142cd594.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62051DGSRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the closest pin-compatible alternative to TPS62051DGSRG4 in this component family?","answer":"Within the TPS6205x family, the TPS62050 is a functional sibling sharing the same pinout and package, but it delivers a fixed output voltage rather than the adjustable output of the TPS62051. The TPS62051DGSRG4 is the adjustable-output variant; the TPS62050 is fixed-output. Footprint and pin compatibility are identical, so a board designed for one can accept the other with a resistor-divider change on the FB pin."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62051DGSRG4","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62051DGSRG4 when reusing this data.
