The 2.12 A switch current is the peak current the internal FET can carry cycle-by-cycle. In step-down mode (VIN > VOUT), the output current can approach the switch rating minus switching losses; in step-up mode (VIN < VOUT), the output current is lower by the boost ratio. For a 3.3 V output from a 2.5 V input, expect roughly 1.5 A continuous output — enough to power a small radio module, a sensor cluster, or an MCU with peripheral load. ## 20-DSBGA footprint and assembly The 20-bump DSBGA uses a 0.4 mm ball pitch. The board requires a fine-line solder mask, a controlled stencil aperture (typically 0.22 mm square), and a reflow profile matched to the SAC305 alloy. This is not a hand-solder part — the assembly needs a pick-and-place line with vision alignment and a nitrogen-capable reflow oven for consistent wetting. The supplier device package is 20-DSBGA, identical to the case code. If the ambient in your enclosure exceeds 85°C, this part is not the fit.","metaTitle":"TPS630242YFFT Buck-Boost Regulator, 2.5 MHz, 2.12 A Switch","metaDescription":"Texas Instruments TPS630242YFFT step-up/step-down regulator, fixed 3.3 V output, 2.5 MHz switching, 2.12 A switch current.","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-Up/Step-Down","Topology":"Buck-Boost","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"20-UFBGA, DSBGA","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"2.12A (Switch)","Number of Outputs":"1","Base Product Number":"TPS630242","Output Configuration":"Positive","Frequency - Switching":"2.5MHz","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":"20-DSBGA","Voltage - Output (Min/Fixed)":"3.3V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.8400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/f0ed9efe966ae82774e461dc64cd2c6a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS630242YFFT/alternatives.json"},"ai":{"faq":[{"question":"Is TPS630242YFFT active or obsolete?","answer":"Active."},{"question":"What is the switching frequency of TPS630242YFFT?","answer":"2.5 MHz.
