The input range spans 2.5 V to 6 V, so it runs cleanly off a single-cell Li-ion (3.0–4.2 V) or a 3.3 V/5 V regulated rail. ## SOT-23-Thin package — board area and reflow profile Housed in a SOT-23-Thin (TSOT-23-5) package, the TPS62222DDCR occupies about 9 mm² of board area. The thin profile (nominal 1.0 mm height) fits into tight enclosures or behind a display bezel. Standard lead-free reflow profile applies; the part is rated MSL-1 per the TI datasheet, so no pre-bake is needed for reels stored dry. The five-pin layout — VIN, GND, EN, SW, FB — is the same as other TPS6222x fixed-output variants, so a single PCB footprint can serve multiple output voltages across the family.","metaTitle":"TPS62222DDCR Step-Down Converter, 400mA, 1.8V Fixed Output","metaDescription":"Texas Instruments TPS62222DDCR buck converter: 1.25MHz switching, 400mA output, fixed 1.8V, SOT-23-Thin, -40°C to 85°C.","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":"Fixed","Mounting Type":"Surface Mount","Package / Case":"SOT-23-5 Thin, TSOT-23-5","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"400mA","Number of Outputs":"1","Base Product Number":"TPS62222","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":"SOT-23-THIN","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.6540","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/e0274b1b9bfa903b303a9f5c4630edbb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62222DDCR/alternatives.json"},"ai":{"faq":[{"question":"What is the switching frequency of TPS62222DDCR?","answer":"The switching frequency is 1.25 MHz.
