The synchronous rectifier is integrated, so no external Schottky catch diode is needed. ## What the 3 A / 2 A rating means for your BOM The 3 A output is the primary rail — typically the core or I/O supply — while the two 2 A outputs handle auxiliary loads like PLL, memory, or peripheral buses. The 0.6 V minimum output lets it feed modern low-voltage cores without an extra LDO. Cut Tape (CT) is also listed for prototype or small-batch orders. ## Package and rework — the QFN reality Reflow profile should follow the JEDEC standard for QFN; the exposed pad needs a good solder joint for both thermal and electrical connection to the ground plane.","metaTitle":"TPS65261-1RHBT Triple Buck Regulator, 3 A / 2 A","metaDescription":"Texas Instruments TPS65261-1RHBT triple synchronous buck regulator, 4.5 V–18 V input, 3 A / 2 A outputs, adjustable 250 kHz–2 MHz, 32-VQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"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":"32-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A, 2A","Number of Outputs":"3","Base Product Number":"TPS65261","Output Configuration":"Positive","Frequency - Switching":"250kHz ~ 2MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"18V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"18V","Supplier Device Package":"32-VQFN (5x5)","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.5900","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/88941989314c8227405662c73bfcbbc8.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65261-1RHBT/alternatives.json"},"ai":{"faq":[{"question":"Can TPS65261-1RHBT replace TPS65261-1RHAR?","answer":"The TPS65261-1RHBT and TPS65261-1RHAR share the same base product number and are functionally identical; the suffix difference indicates packaging or reel quantity.
