Rated for 2A continuous output, this part handles a typical 3.3V rail powering an MCU plus a few peripherals — think Cortex-M4 with a radio module or a small FPGA core supply. The 2A ceiling leaves headroom for inrush without hitting current limit. Switching frequency runs between 1.5 MHz and 2.5 MHz, which keeps the inductor physically small — a 1 µH to 2.2 µH shielded inductor in the 0806 or 1008 footprint fits. The higher end of that band pushes switching losses up slightly but shrinks the output capacitor count. ## 11-VFQFN-HR (2x2) — footprint and thermal reality The 11-VFQFN-HR package measures 2 mm x 2 mm — a compact land pattern that demands a 4-layer board for the thermal via array under the exposed pad. The centre pad is the primary heat path; without a solid via cluster to the ground plane, the junction temperature climbs fast above 1 A. The junction-to-ambient thermal resistance depends heavily on the PCB copper area — budget a 1-inch-square copper pour on the bottom layer if you plan to run near 2 A at 85°C ambient.","metaTitle":"TI TPS6209733RWKT Step-Down Regulator, 3.3V Fixed, 2A","metaDescription":"Texas Instruments TPS6209733RWKT buck converter, fixed 3.3V output, 2A, iDCS-Control, 11-VFQFN, -40 to 125°C.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"iDCS-Control","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"11-VFQFN","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"2A","Number of Outputs":"1","Base Product Number":"TPS6209733","Output Configuration":"Positive","Frequency - Switching":"1.5MHz ~ 2.5MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"-","Supplier Device Package":"11-VQFN-HR (2x2)","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.2700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0b0f6bd481e94727c8e75b07272aa942.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS6209733RWKT/alternatives.json"},"ai":{"faq":[{"question":"What is the exact fixed output voltage of TPS6209733RWKT?","answer":"The fixed output voltage is 3.3V.
