That switching frequency is the headline spec: it lets you use a 0.47 µH or 1 µH inductor and 4.7 µF output cap in 0402 or 0603 case sizes, collapsing the power-stage footprint to roughly the area of the DSBGA package itself. For space-constrained designs — wearables, IoT nodes, handheld instruments — this is the regulator that fits where a lower-frequency part would need twice the board real estate. ## 1 A continuous — load budget and thermal reality Rated for 1 A continuous output. In a 6-DSBGA package with no exposed pad, the thermal path is through the solder bumps and the PCB copper. ## Input range and output — what the BOM sees Output is fixed at 1.2 V — no resistor divider, no feedback trim. ## DSBGA layout — what the board needs 6-bump DSBGA, 0.5 mm pitch. The bumps are solder-mask-defined; the PCB pad diameter should be 0.25 mm with a 0.3 mm solder-mask opening. Route the input cap (4.7 µF, 0603) within 2 mm of the VIN bump, output cap similarly close to VOUT. The 6 MHz edge rate demands short loops — a 10 nF high-frequency bypass cap directly at the IC bumps is not optional. Stencil aperture for the bumps should be 0.28 mm square, 100 µm thick. ## Lifecycle and ordering No direct replacement or second-source alternate is listed by TI, but the TPS62665 family shares the same pinout and control loop, so other fixed-output voltage variants (0.8 V, 1.5 V, 1.8 V, 2.5 V, 3.3 V) are drop-in compatible if the output voltage changes.","metaTitle":"TPS62665YFFR 6-MHz 1-A Step-Down Buck Converter, 6-DSBGA","metaDescription":"Texas Instruments TPS62665YFFR step-down buck converter, fixed 1.2 V output, 1 A, 6 MHz switching, 6-DSBGA package.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Mfr":"Texas Instruments","Series":"-","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-UFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"1A","Number of Outputs":"1","Base Product Number":"TPS62665","Output Configuration":"Positive","Frequency - Switching":"6MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.3V","Voltage - Output (Max)":"-","Supplier Device Package":"6-DSBGA","Voltage - Output (Min/Fixed)":"1.2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.8565","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f6c67c76faaab1b02a9530b4c27bc30d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62665YFFR/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS62665YFFR and TPS62665YFFT?","answer":"The TPS62665YFFR and TPS62665YFFT are the same silicon in the same 6-DSBGA package.
