The output is fixed at 1.8 V — no external resistor divider for feedback, which saves two components and one node that could pick up noise.","metaTitle":"TPS62231DRYT 3 MHz 500 mA Step-Down Converter, 6-SON","metaDescription":"Texas Instruments TPS62231DRYT 3 MHz synchronous buck regulator, fixed 1.8 V output, 500 mA, -40 to 125°C, 6-SON.","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-UFDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"500mA","Number of Outputs":"1","Base Product Number":"TPS62231","Output Configuration":"Positive","Frequency - Switching":"3MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.05V","Voltage - Output (Max)":"-","Supplier Device Package":"6-SON (1.45x1)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6100","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d4bd0b976f6974a22ac776d1e67c96a3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62231DRYT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS62231DRYT a direct replacement for TPS62230?","answer":"The TPS62230 and TPS62231 are in the same family (base number TPS62231) and share the same package and pinout.
