The fixed 3.3V output simplifies the feedback network — no external resistor divider is needed. Any replacement must be evaluated for pin-compatibility, output voltage, current rating, and switching frequency against the original design. ## Package and thermal — 10-VSON with exposed pad No tube or tray options are listed for this order code.","metaTitle":"TPS62046DRCRG4 Buck Regulator, 1.2A, 3.3V Fixed, Obsolete","metaDescription":"Texas Instruments TPS62046DRCRG4 step-down buck regulator, 1.2A output, 3.3V fixed, 1.25MHz switching.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","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-VFDFN Exposed Pad","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Current - Output":"1.2A","Number of Outputs":"1","Base Product Number":"TPS620","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":"$50.4500","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/3a54d04aa330c6ddd3c5f782f778189e.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62046DRCRG4/alternatives.json"},"ai":{"faq":[{"question":"What is a replacement for TPS62046DRCRG4?","answer":"No official replacement part number is listed by Texas Instruments.
