That makes this part a fit for space-constrained portable or RF power rails where board area is the binding constraint, not raw efficiency. ## 1 A output at 1.2 V — load budget and thermal reality With a fixed 1.2 V output and 1 A continuous rating, the TPS62665YFFT is sized for low-voltage core and I/O rails — think a 1.2 V DDR termination, an FPGA VCCINT rail, or a wireless SoC's digital supply. ## 6-DSBGA — layout constraints for the board designer Fan-out requires micro-vias (laser-drilled, 0.2 mm pad diameter) on a minimum 2-layer PCB; a 4-layer stack with a ground plane under the package improves thermal spreading. The input and output capacitors must sit within 2 mm of the package to keep the 6 MHz switching loop inductance below 2 nH.","metaTitle":"TPS62665YFFT 6 MHz Buck Converter, 1 A, 6-DSBGA","metaDescription":"TI TPS62665YFFT step-down buck converter, 6 MHz switching, 1 A output, fixed 1.2 V, -40 to 85°C, 6-DSBGA.","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":"$2.1400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f6c67c76faaab1b02a9530b4c27bc30d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62665YFFT/alternatives.json"},"ai":{"faq":[{"question":"Can TPS62665YFFT be used for 5V to 3.3V conversion?","answer":"No — the TPS62665YFFT has a fixed 1.2 V output.
