The programmable output voltage is set to either 1.2 V or 1.8 V, targeting low-voltage core rails for MCUs, Bluetooth LE SoCs, and sensor nodes. ## 1.2 MHz switching — inductor size and ripple trade-off The 1.2 MHz switching frequency lets the designer use a small inductor (2.2 µH to 4.7 µH range) and keeps the fundamental ripple above the audio band. The trade-off is higher switching losses at very light loads — below 10 mA the efficiency curve drops faster than a 600 kHz part would. ## 125°C junction — industrial and automotive edge The 8-DSBGA package (0.4 mm ball pitch) requires a controlled solder profile and a clean PCB surface finish — ENIG or OSP, not bare copper. The base product number TPS62748 covers multiple output-voltage and package variants, so a future BOM respin to a sibling code is possible without a full qualification cycle.","metaTitle":"TPS62748YFPT 300 mA Step-Down Buck Converter, 8-DSBGA","metaDescription":"TI TPS62748YFPT step-down buck converter, 300 mA output, 1.2 MHz switching, -40°C to 125°C TJ.","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":"Programmable","Mounting Type":"Surface Mount","Package / Case":"8-XFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"300mA","Number of Outputs":"1","Base Product Number":"TPS62748","Output Configuration":"Positive","Frequency - Switching":"1.2MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.15V","Voltage - Output (Max)":"-","Supplier Device Package":"8-DSBGA","Voltage - Output (Min/Fixed)":"1.2V, 1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.7400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/57c139a243ce998f547acb8c8c95dbbb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62748YFPT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS62748YFPT the same as TPS62748YFPR?","answer":"The TPS62748YFPT and TPS62748YFPR share the same base product number TPS62748 and the same 8-DSBGA package. The suffix difference (PT vs PR) typically indicates a different tape-and-reel packing quantity or reel diameter. Functionally they are identical — the same die, same electrical specs. Confirm the reel quantity with your distributor before ordering."},{"question":"Can TPS62748YFPT be used in a 2-cell battery application?","answer":"Yes. The input voltage range of 2.15 V to 5.5 V covers a 2-cell alkaline stack (2.4 V fresh down to 2.0 V depleted) and a 2-cell NiMH stack (2.4 V nominal). The minimum input of 2.15 V leaves headroom for the 1.8 V output option. For a 2-cell Li-ion stack (7.4 V nominal), the 5.5 V maximum input is exceeded — that application needs a different converter."},{"question":"Does TPS62748YFPT come in a tape and reel package?","answer":"The 8-DSBGA package is a wafer-level chip-scale package, so the tape pocket is designed for the bare die footprint with no molded body. The reel quantity varies by the TR suffix — confirm the exact count with the distributor."},{"question":"Is TPS62748YFPT RoHS compliant?","answer":"No explicit RoHS certification code appears in this listing, but the DSBGA package is lead-free by design. Verify the date-code-specific RoHS status on the manufacturer's website or request a certificate of compliance with your order."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62748YFPT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62748YFPT when reusing this data.
