That shrinks the total footprint around the 10-VSON (3×3 mm) package — a meaningful advantage when board area is the constraint. Output is adjustable from a 0.7 V reference up to the input voltage. For a 1.8 V rail — a common core or I/O supply — the feedback divider uses two resistors; the part can deliver that voltage across the full 1.2 A load.","metaTitle":"TPS62040DRCRG4 Buck Converter, 1.2 A, 1.25 MHz, Synchronous","metaDescription":"Texas Instruments TPS62040DRCRG4 step-down buck converter, 1.2 A output, 1.25 MHz switching, synchronous rectification, -40°C to 85°C, 10-VSON.","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":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"1.2A","Number of Outputs":"1","Base Product Number":"TPS62040","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)":"6V","Supplier Device Package":"10-VSON (3x3)","Voltage - Output (Min/Fixed)":"0.7V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$50.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a54d04aa330c6ddd3c5f782f778189e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62040DRCRG4/alternatives.json"},"ai":{"faq":[{"question":"Can TPS62040DRCRG4 output 1.8 V?","answer":"Yes.
