For a board where every mm² is budgeted (wearable, IoT sensor, portable medical), this part saves real estate over a 1-2 MHz regulator that needs a 4.7 µH inductor and 10 µF cap. ## Fixed 1.5 V rail — core supply for low-voltage logic Output is fixed at 1.5 V — no external resistor divider needed. That voltage is a common core supply for FPGAs, MCUs, and wireless SoCs (e.g., CC13xx, certain STM32L4 parts). If your BOM calls for an adjustable output, this fixed version won't fit; look at the TPS62612 adjustable variant instead. ## Input range and current — battery to regulated bus The 350 mA output is sized for a small FPGA core (e.g., iCE40UP5K) or a wireless module drawing 200-300 mA peak. At 350 mA continuous, the 6-DSBGA package's thermal impedance (approx 150 °C/W) keeps junction temperature under 100 °C at 85 °C ambient — no derating needed for most designs. ## 6-DSBGA — footprint and layout The 6-DSBGA (0.9 mm × 1.3 mm typical, 0.4 mm pitch) is a wafer-level chip-scale package. No exposed pad — all six balls carry the thermal path through the PCB vias. A 4-layer board with thermal vias under the package is recommended; a 2-layer board can work if the output current stays below 200 mA and the ambient is under 60 °C. The solder paste stencil aperture should match the ball diameter (0.25 mm typical) to avoid bridging.","metaTitle":"TPS62612YFDT Texas Instruments Step-Down Buck, 6 MHz, 350 mA","metaDescription":"Texas Instruments TPS62612YFDT step-down buck regulator, fixed 1.5 V output, 350 mA, 6 MHz switching, 2.3-5.5 V input, -40 to 85°C, 6-DSBGA package.","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":"Fixed","Mounting Type":"Surface Mount","Package / Case":"6-XFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"350mA","Number of Outputs":"1","Base Product Number":"TPS62612","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)":"1.5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$0.9103","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/aa01fdb2bc692d3bd78b8ff825207e1b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62612YFDT/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62612YFDT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62612YFDT when reusing this data.
