Output is adjustable from 0.4V up to 5.5V via an external resistor divider, making it suitable for powering 1.8V, 3.3V, or 5V sensor/interface rails from the same BOM. ## Switching frequency and inductor trade-off The device can be set to either 1 MHz or 2.5 MHz switching frequency via a pin-strap resistor. At 2.5 MHz the inductor value drops below 1 µH, shrinking the total solution footprint to fit the SOT-583 package's 2.0 mm × 2.0 mm body. The 1 MHz setting improves efficiency by about 2-3% at 12V input, a worthwhile trade when the board has room for a 2.2 µH inductor. ## Temperature grade and under-hood deployment ROHS3 compliant and AEC-Q100 qualified — the Q1 suffix confirms automotive-grade release, which also means the part is manufactured on a dedicated automotive line with tighter process controls.","metaTitle":"TPS629206QDRLRQ1 Buck Regulator 600mA SOT-583 Automotive","metaDescription":"Texas Instruments TPS629206QDRLRQ1 step-down buck regulator, 3V to 17V input, 600 mA output, adjustable 0.4V to 5.5V, -40°C to 150°C, 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":"600mA","Number of Outputs":"1","Base Product Number":"TPS629206","Output Configuration":"Positive","Frequency - Switching":"1MHz, 2.5MHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"17V","Voltage - Input (Min)":"3V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"SOT-583","Voltage - Output (Min/Fixed)":"0.4V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6300","priceTiers":[{"qty":1,"price":"$1.63000","currency":"USD"},{"qty":10,"price":"$1.46000","currency":"USD"},{"qty":25,"price":"$1.38560","currency":"USD"},{"qty":100,"price":"$1.13830","currency":"USD"},{"qty":250,"price":"$1.06404","currency":"USD"},{"qty":500,"price":"$0.94032","currency":"USD"},{"qty":1000,"price":"$0.74235","currency":"USD"},{"qty":4000,"price":"$0.66458","currency":"USD"},{"qty":8000,"price":"$0.63135","currency":"USD"},{"qty":12000,"price":"$0.60762","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/bfcb9005c8627956d4cd05e8a4a64d71.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS629206QDRLRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS629206QDRLRQ1 a direct replacement for the base TPS629206?","answer":"Yes — the QDRLRQ1 suffix denotes the SOT-583 package and tape-and-reel format.
