The 2.2MHz switching frequency lets you keep the output inductor in the 1 µH range and the ceramic capacitors small, which saves board area on a dense 6-VSON-HR (1.5x1.5) footprint. ## 3 A output, 2.2 MHz switching, 125°C junction At 3A output and 2.2MHz, the switching losses start to dominate the thermal budget above 3.6V input — plan the copper pour on the VSON pad to keep junction below 125°C. ## Active production, ROHS3, 6-VSON-HR package The 6-VSON-HR package (1.5x1.5 mm) has an exposed thermal pad; the datasheet recommends a 2-layer or 4-layer board with thermal vias under the pad to get the rated 3A out without hitting thermal shutdown. Tape & Reel and Cut Tape options are available for prototyping and volume.","metaTitle":"TPS6282618DMQT 1.8V 3A Buck Regulator - TI Active","metaDescription":"Texas Instruments TPS6282618DMQT step-down buck regulator, fixed 1.8V output, 3A, 2.2MHz switching, 6-VSON-HR (1.5x1.5) package, -40°C to 125°C junction.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-VFDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Base Product Number":"TPS6282618","Output Configuration":"Positive","Frequency - Switching":"2.2MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.4V","Voltage - Output (Max)":"-","Supplier Device Package":"6-VSON-HR (1.5x1.5)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0100","priceTiers":[{"qty":1,"price":"$2.01000","currency":"USD"},{"qty":10,"price":"$1.80600","currency":"USD"},{"qty":25,"price":"$1.70400","currency":"USD"},{"qty":100,"price":"$1.45180","currency":"USD"},{"qty":250,"price":"$1.36316","currency":"USD"},{"qty":500,"price":"$1.19276","currency":"USD"},{"qty":1250,"price":"$0.98829","currency":"USD"},{"qty":2500,"price":"$0.96450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ef2a5a07e2ca5eeccaa6953b31e1f890.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS6282618DMQT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS6282618DMQT obsolete?","answer":"No, it carries an active lifecycle status."},{"question":"Is TPS6282618DMQT compatible with 5V input?","answer":"Yes, the input voltage range is 2.4V to 5.5V, so 5V is within the operating range."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS6282618DMQT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS6282618DMQT when reusing this data.
