The synchronous rectifier (integrated low-side FET) eliminates the external Schottky diode. ## Package and thermal — the exposed pad matters The 10-HVSSOP (3.00 mm × 3.00 mm) has an exposed thermal pad on the bottom. Without the pad soldered to a thermal land, the part derates significantly above 85 °C ambient.","metaTitle":"TPS62044DGQR Step-Down Regulator, 1.25 MHz, 1.2 A, 10-HVSSOP","metaDescription":"Texas Instruments TPS62044DGQR fixed-output buck converter: 2.5-6 V input, 1.8 V output, 1.2 A, 1.25 MHz switching, -40 to 85 °C, 10-HVSSOP.","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":"TPS62044","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)":"1.8V"}},"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/TPS62044DGQR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62044DGQR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62044DGQR when reusing this data.
