For a 12V-to-3.3V conversion at 3A, the efficiency typically stays above 90% across most of the load range, which keeps the SOT-583 package within its thermal limits without forced airflow. ## Switching frequency range and output adjustability A 2.2 MHz setting shrinks the inductor to a 1 µH or 2.2 µH footprint, useful when board height is constrained. That tight reference tolerance keeps the output accurate enough for a 1.2V core rail without post-regulation. The SOT-583 package is RoHS3 compliant, with no halogen or antimony declarations beyond the standard TI material disclosure. ## SOT-583 footprint and layout notes The SOT-583 package is an 8-pin, 0.5 mm pitch, 1.6 mm × 1.6 mm body. The input capacitor should be placed within 2 mm of the VIN pin to minimise input ripple; the datasheet layout example uses a 10 µF X7R ceramic.","metaTitle":"TPS62933ODRLR TI Buck Regulator 3A Adjustable SOT-583","metaDescription":"Texas Instruments TPS62933ODRLR step-down buck regulator, 3.8V–30V input, 3A output, adjustable, synchronous rectifier, SOT-583, active production.","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":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"SOT-583","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"200kHz ~ 2.2MHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"30V","Voltage - Input (Min)":"3.8V","Voltage - Output (Max)":"22V","Supplier Device Package":"SOT-583","Voltage - Output (Min/Fixed)":"0.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.7600","priceTiers":[{"qty":1,"price":"$0.76000","currency":"USD"},{"qty":10,"price":"$0.66700","currency":"USD"},{"qty":25,"price":"$0.62640","currency":"USD"},{"qty":100,"price":"$0.51110","currency":"USD"},{"qty":250,"price":"$0.47472","currency":"USD"},{"qty":500,"price":"$0.40400","currency":"USD"},{"qty":1000,"price":"$0.32320","currency":"USD"},{"qty":4000,"price":"$0.29290","currency":"USD"},{"qty":8000,"price":"$0.27270","currency":"USD"},{"qty":12000,"price":"$0.26260","currency":"USD"},{"qty":28000,"price":"$0.25250","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/5bf33c4db24192eb8dd5010f33645ec9.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62933ODRLR/alternatives.json"},"ai":{"faq":[{"question":"Does TPS62933ODRLR require external switching MOSFETs?","answer":"No. The TPS62933ODRLR integrates both the high-side and low-side MOSFETs with a synchronous rectifier.
