If your downstream circuit peaks at 1 A, you have 20 % headroom at 25 °C — but the 10-HVSSOP package's thermal impedance means that headroom shrinks as ambient temperature climbs. At 85 °C, the available output current before the thermal shutdown threshold is lower than the headline 1.2 A; a layout with a solid ground-plane pad and via array under the exposed pad directly buys you back that margin. ## Industrial temperature range – where it fits It is not suited for under-hood engine bay or military avionics environments that demand -55°C to 125°C or 150°C junction ratings. For a factory-floor sensor rail or a base-station line card, the temperature grade is a clean match. ## Active lifecycle – no obsolescence watch needed For a BOM line committed to production, this part does not carry a near-term supply risk.","metaTitle":"TPS62046DGQR Step-Down Buck Regulator, 1.2 A, 1.25 MHz","metaDescription":"Texas Instruments TPS62046DGQR step-down buck regulator, 1.2 A output, 1.25 MHz switching frequency, fixed 3.3 V output, -40°C to 85°C, 10-HVSSOP 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":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","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":"TPS62046","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)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a54d04aa330c6ddd3c5f782f778189e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62046DGQR/alternatives.json"},"ai":{"faq":[{"question":"What is the switching frequency of TPS62046DGQR?","answer":"The switching frequency is 1.25 MHz.
