Its input range of 2.7V to 6V makes it a fit for 3.3V and 5V automotive rails, including pre-regulated supplies from battery or intermediate buses. The AEC-Q100 qualification confirms it for production-grade automotive applications. ## Switching frequency flexibility and inductor sizing Four selectable switching frequencies — 1.5 MHz, 2.25 MHz, 2.5 MHz, and 3 MHz — let the designer trade off inductor size against efficiency. At 3 MHz the inductor can drop below 1 µH, shrinking the total solution footprint, while 1.5 MHz improves light-load efficiency in always-on modules. The 16-VQFN (2.55x3.55 mm) package with wettable flanks supports automated optical inspection (AOI) in high-volume assembly. It is ROHS3 compliant.","metaTitle":"TPS62870Y3QWRXSRQ1 6A Buck Converter – AEC-Q100","metaDescription":"Texas Instruments TPS62870Y3QWRXSRQ1 – Automotive AEC-Q100 synchronous buck regulator, 6A output, 0.4V-3.35V programmable, -40°C to 125°C, 16-VQFN.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR) Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Programmable","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"16-TFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"6A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"1.5MHz, 2.25MHz, 2.5MHz, 3MHz","Operating Temperature":"-40°C ~ 125°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"3.35V","Supplier Device Package":"16-VQFN (2.55x3.55)","Voltage - Output (Min/Fixed)":"0.4V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.0100","priceTiers":[{"qty":1,"price":"$4.01000","currency":"USD"},{"qty":10,"price":"$3.60100","currency":"USD"},{"qty":25,"price":"$3.40440","currency":"USD"},{"qty":100,"price":"$2.95030","currency":"USD"},{"qty":250,"price":"$2.79900","currency":"USD"},{"qty":500,"price":"$2.51154","currency":"USD"},{"qty":1000,"price":"$2.11817","currency":"USD"},{"qty":3000,"price":"$2.01226","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/0af31116bc15c3dee4e7a23c68532911.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62870Y3QWRXSRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS62870Y3QWRXSRQ1 compatible with a 5V input?","answer":"Yes, the input voltage range is 2.7V to 6V, so a 5V rail is well within the operating window with margin."},{"question":"How does TPS62870Y3QWRXSRQ1 compare to LMR33630APCQRNXRQ1?","answer":"Both are AEC-Q100 automotive synchronous buck converters.
