At 500 mA output, the ripple current stays within 30% of the load, keeping the output capacitor count to a single 10 µF ceramic. ## Input voltage range and rail compatibility The input range spans 2.05 V to 6 V, covering single-cell Li-Ion (3.0 V–4.2 V), 3.3 V, and 5 V rails. The 2.05 V minimum means it can run from a nearly discharged Li-Ion cell, though the dropout at low input voltage will limit the available output current. Sourced per RFQ against BOM quantities.","metaTitle":"TPS622319DRYT Buck Converter 500mA 2MHz Texas Instruments","metaDescription":"Texas Instruments TPS622319DRYT step-down buck regulator: 2.05V-6V input, fixed 1.2V output, 500mA, 2MHz switching, -40°C to 125°C, 6-SON (1.45x1) 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":"6-UFDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"500mA","Number of Outputs":"1","Base Product Number":"TPS622319","Output Configuration":"Positive","Frequency - Switching":"2MHz","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)":"1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6100","priceTiers":[{"qty":1,"price":"$1.61000","currency":"USD"},{"qty":10,"price":"$1.44400","currency":"USD"},{"qty":25,"price":"$1.36200","currency":"USD"},{"qty":100,"price":"$1.16050","currency":"USD"},{"qty":250,"price":"$1.08968","currency":"USD"},{"qty":500,"price":"$0.95348","currency":"USD"},{"qty":1250,"price":"$0.79002","currency":"USD"},{"qty":2500,"price":"$0.77100","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/d4bd0b976f6974a22ac776d1e67c96a3.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS622319DRYT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS622319DRYT compatible with 3.3 V input?","answer":"Yes, 3.3 V is within the 2.05 V to 6 V input range.
