The 1.8 MHz to 4 MHz switching frequency lets you keep the inductor small — a 0.47 µH to 2.2 µH part usually fits — while the 9-VQFN-HR (3x2) package with wettable flanks eases AOI inspection on automotive boards. ## Thermal and switching trade-offs At 6 A and 3.3 V out from 5 V in, expect efficiency in the mid-90 % range — the exact number depends on the inductor DCR and switching frequency selected. Compared to the LMR33630APCQRNXRQ1 (3 A, 2.1 MHz fixed), the TPS62816QWRWYRQ1 doubles the output current and offers a wider adjustable frequency range, but the LMR33630 runs at a lower fixed frequency that may suit noise-sensitive loads.","metaTitle":"TPS62816QWRWYRQ1 – 6A Buck Regulator, AEC-Q100, 9-VQFN","metaDescription":"Texas Instruments TPS62816QWRWYRQ1: automotive step-down buck regulator, 6 A output, 2.7–6 V input, adjustable output, -40°C to 125°C, 9-VQFN-HR.","metaKeywords":null},"attributes":{"series":"Automotive, AEC-Q100","packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","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":"Adjustable","Mounting Type":"Surface Mount, Wettable Flank","Package / Case":"9-VFQFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"6A","Number of Outputs":"1","Base Product Number":"TPS62816","Output Configuration":"Positive","Frequency - Switching":"1.8MHz ~ 4MHz","Operating Temperature":"-40°C ~ 125°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.7V","Voltage - Output (Max)":"5.5V","Supplier Device Package":"9-VQFN-HR (3x2)","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1600","priceTiers":[{"qty":1,"price":"$3.16000","currency":"USD"},{"qty":10,"price":"$2.83600","currency":"USD"},{"qty":25,"price":"$2.68160","currency":"USD"},{"qty":100,"price":"$2.32400","currency":"USD"},{"qty":250,"price":"$2.20484","currency":"USD"},{"qty":500,"price":"$1.97838","currency":"USD"},{"qty":1000,"price":"$1.66852","currency":"USD"},{"qty":3000,"price":"$1.58509","currency":"USD"},{"qty":6000,"price":"$1.52550","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/2c1b17d4495d947903faf36a7a4dc8dd.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62816QWRWYRQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS62816QWRWYRQ1 a drop-in replacement for TPS62816QRWYRQ1?","answer":"The base product number is TPS62816 for both. The 'Q' suffix indicates AEC-Q100 qualification. The 'WRWYR' package code is identical (9-VQFN-HR). Pinout and function are the same — the difference is the automotive qualification on the QWRWYR variant. Confirm with the datasheet before committing a board spin."},{"question":"How does TPS62816QWRWYRQ1 compare to the TPS62817?","answer":"The TPS62817 is a higher-current sibling (typically 8 A or 10 A in the same package family). The TPS62816QWRWYRQ1 is rated 6 A continuous. Efficiency curves overlap at lower loads, but at full load the TPS62817 runs cooler.
