The 1.2 A output is a hard ceiling — if your transient peak exceeds that, the LM53625LQURNLRQ1 (2.5 A) or LMR33630APCQRNXRQ1 (3.0 A) are pin-compatible alternatives in similar packages, though both carry automotive AEC-Q100 qualification and a wider temperature range. The 10-VSON (3x3) package is a current, widely used footprint — no supply chain surprise.","metaTitle":"TPS62046DRCR Buck Regulator 3.3V 1.2A Active - Texas","metaDescription":"TPS62046DRCR step-down buck regulator, fixed 3.3 V output, 1.2 A continuous, 1.25 MHz switching, -40°C to 85°C, 10-VSON package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","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-VFDFN Exposed Pad","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-VSON (3x3)","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3900","priceTiers":[{"qty":1,"price":"$2.39000","currency":"USD"},{"qty":10,"price":"$2.14300","currency":"USD"},{"qty":25,"price":"$2.02200","currency":"USD"},{"qty":100,"price":"$1.72270","currency":"USD"},{"qty":250,"price":"$1.61756","currency":"USD"},{"qty":500,"price":"$1.41536","currency":"USD"},{"qty":1000,"price":"$1.17273","currency":"USD"},{"qty":3000,"price":"$1.14450","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/20bfea69ef4989277f0a4b148a35b1d7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62046DRCR/alternatives.json"},"ai":{"faq":[{"question":"What are the closest functional alternatives to TPS62046DRCR?","answer":"For higher output current, the LM53625LQURNLRQ1 (2.5 A) and LMR33630APCQRNXRQ1 (3.0 A) are buck regulators with similar input voltage ranges and synchronous rectification, both AEC-Q100 qualified. They are not exact pin-to-pin matches — verify the package and pinout against your layout before substituting."},{"question":"What input voltage range does TPS62046DRCR support?","answer":"The TPS62046DRCR operates from 2.5 V to 6 V input. That covers single-cell Li-ion, two-cell alkaline, and 5 V regulated rails, but not 12 V or higher buses."},{"question":"Can TPS62046DRCR be used in battery-powered devices?","answer":"Yes. The 2.5 V minimum input works with a single Li-ion cell (3.0-4.2 V), and the 1.25 MHz switching frequency allows small external components that fit portable designs. The synchronous rectifier improves efficiency at light loads, extending battery run time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62046DRCR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62046DRCR when reusing this data.
