That saves two components and one feedback-node routing headache. The synchronous rectifier improves efficiency at light loads, which is relevant for battery-powered or always-on systems where quiescent current matters.","metaTitle":"Texas Instruments TPS62044DGQRG4 Step-Down Regulator, 1.2 A","metaDescription":"Texas Instruments TPS62044DGQRG4 synchronous buck regulator, 1.2 A output, 1.25 MHz switching, fixed 1.8 V, -40°C 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)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-PowerTFSOP, 10-MSOP (0.118\\\", 3.00mm Width)","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":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a54d04aa330c6ddd3c5f782f778189e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62044DGQRG4/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS62044DGQRG4 and TPS62044DGQR?","answer":"The suffix 'G4' on the TPS62044DGQRG4 indicates a lead-free (RoHS-compliant) finish variant.
