It delivers a fixed 1.8V output at up to 1A from an input range of 3V to 17V, switching at 2.5MHz. The fixed output voltage eliminates the external feedback divider, which saves two resistors and one feedback-node capacitor from the BOM — useful when the 1.8V rail is the only low-voltage rail on the board and board space is tight. ## Sizing the 1A rail — load budget and thermal margin The 1A output rating is the continuous current limit. For a rail feeding a small FPGA core or a set of MCU I/O banks, budget the total load at no more than 800 mA to keep junction temperature rise within the 85°C ambient ceiling. The 2.5MHz switching frequency lets the output inductor and capacitor shrink — a 2.2 µH to 4.7 µH inductor in the 0805 or 1210 footprint works, and the output cap can be a single 22 µF ceramic.","metaTitle":"TPS62151RGTR Step-Down Regulator, 1A, Fixed 1.8V Output","metaDescription":"Texas Instruments TPS62151RGTR synchronous buck regulator, 3V–17V input, 1A output, fixed 1.8V, DCS-Control, 2.5MHz switching, QFN package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"DCS-Control™","Package":"Tape & Reel (TR)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"16-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"1A","Number of Outputs":"1","Base Product Number":"TPS62151","Output Configuration":"Positive","Frequency - Switching":"2.5MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"17V","Voltage - Input (Min)":"3V","Voltage - Output (Max)":"-","Supplier Device Package":"16-VQFN (3x3)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6301c4053bf3fe70270b463c5cd5970c.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62151RGTR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS62151RGTR compatible with TPS62150?","answer":"The TPS62150 is the adjustable-output version of the same basic regulator. Both share the same pinout, package (16-VFQFN 3x3 mm), input range, and switching frequency. The difference is the feedback path: the TPS62151RGTR has a fixed 1.8V output internally, while the TPS62150 uses an external resistor divider to set the output voltage. If your BOM needs a different rail voltage, the TPS62150 is the pin-compatible alternative."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62151RGTR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62151RGTR when reusing this data.
