The 1.2A output current handles moderate loads like MCU core rails, sensor supplies, or low-power RF stages. Derate the current above 85°C ambient per the datasheet's thermal derating curve; the 10-HVSSOP package's exposed pad helps pull heat to the board copper.","metaTitle":"TPS62042DGQ Buck Converter, 1.2A, 1.25MHz, Fixed 1.5V Output","metaDescription":"Texas Instruments TPS62042DGQ step-down DC-DC converter: 2.5V-6V input, fixed 1.5V output, 1.2A, 1.25MHz, synchronous rectification, -40°C to 85°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":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-PowerTFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"1.2A","Number of Outputs":"1","Base Product Number":"TPS62042","Output Configuration":"Positive","Frequency - Switching":"1.25MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"-","Supplier Device Package":"10-HVSSOP","Voltage - Output (Min/Fixed)":"1.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a54d04aa330c6ddd3c5f782f778189e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62042DGQ/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62042DGQ","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62042DGQ when reusing this data.
