The 2.2 MHz switching frequency keeps the inductor small enough to fit a 1.5x1.5 mm VSON package layout without sacrificing efficiency. ## Output adjustability and thermal range Output voltage is adjustable from 0.6 V up to 4 V, so it can power a 1.2 V core rail, a 1.8 V I/O rail, or a 3.3 V peripheral rail from the same BOM entry. Synchronous rectification is built in, which means no external Schottky diode and a higher efficiency at light loads. The 6-VSON-HR package (1.5x1.5 mm) with an exposed pad pulls heat into the PCB copper — the thermal pad layout is the one thing to get right on the board. ## How it compares to a similar automotive-grade buck The LMR33630APCQRNXRQ1 is an automotive AEC-Q100 buck with the same 3 A output and a similar 2.1 MHz switching frequency, but its input range starts at 3.8 V — so it cannot run from a 2.4 V rail. The TPS62826DMQR's wider 2.4 V minimum input lets it operate from a single Li-ion cell or a 3.3 V rail with margin, while the LMR33630 needs a 5 V bus or higher.","metaTitle":"TPS62826DMQR Buck Regulator 3A 2.2MHz 6-VSON","metaDescription":"Texas Instruments TPS62826DMQR step-down buck regulator, adjustable output, 3 A, 2.2 MHz switching, 6-VSON-HR (1.5x1.5) 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":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"6-VFDFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Base Product Number":"TPS62826","Output Configuration":"Positive","Frequency - Switching":"2.2MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.4V","Voltage - Output (Max)":"4V","Supplier Device Package":"6-VSON-HR (1.5x1.5)","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.6800","priceTiers":[{"qty":1,"price":"$1.68000","currency":"USD"},{"qty":10,"price":"$1.50600","currency":"USD"},{"qty":25,"price":"$1.42040","currency":"USD"},{"qty":100,"price":"$1.21020","currency":"USD"},{"qty":250,"price":"$1.13632","currency":"USD"},{"qty":500,"price":"$0.99428","currency":"USD"},{"qty":1000,"price":"$0.82383","currency":"USD"},{"qty":3000,"price":"$0.80400","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ef2a5a07e2ca5eeccaa6953b31e1f890.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62826DMQR/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62826DMQR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62826DMQR when reusing this data.
