The output is fixed at 1.8 V — no external feedback divider needed. The positive output configuration and single-channel architecture suit point-of-load regulation for low-voltage digital cores or I/O banks. ## 6-WSON exposed-pad thermal management The 6-WDFN with exposed pad (6-WSON 2x2 mm) is a surface-mount package that relies on the PCB copper plane under the pad for heat sinking. No second-source or successor part is documented for this exact fixed-output variant.","metaTitle":"Texas Instruments TPS62243DRVT Step-Down Buck Regulator","metaDescription":"TI TPS62243DRVT is a 300 mA synchronous step-down buck converter with fixed 1.8V output, 2.25 MHz switching, 6-WSON package.","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":"6-WDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"300mA","Number of Outputs":"1","Base Product Number":"TPS62243","Output Configuration":"Positive","Frequency - Switching":"2.25MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2V","Voltage - Output (Max)":"-","Supplier Device Package":"6-WSON (2x2)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/8fc6cee8f4e56d8678c239fa05de7339.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62243DRVT/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS62243DRVT and TPS62243DRVR?","answer":"The base part TPS62243 is the same IC; the suffix DRVT vs DRVR indicates different packaging options (Tape & Reel vs Cut Tape or different reel quantities).
