The integrated switch is rated for 2A, which sets the practical output current ceiling — at 5V out from a 3.3V input, the switch current limit allows roughly 1.2A continuous output before hitting the 2A switch peak, depending on inductor ripple and efficiency. This part suits single-cell Li-ion to 5V USB rails, 2- or 3-cell alkaline boost, or 3.3V to 5V point-of-load conversion in portable and industrial gear. ## Synchronous rectification and switching frequency Synchronous rectification replaces the external Schottky diode with a second internal FET, improving efficiency by 3–5% at moderate loads compared to a diode-based boost. The 600kHz switching frequency is a practical middle ground — it keeps the inductor small (typically 4.7 µH to 10 µH) while staying below the 1 MHz band where switching losses start to dominate in a 2A boost. It does not carry an AEC-Q100 automotive qualification, so it is not specified for under-hood or chassis-mounted automotive applications. For a 5V rail in a factory sensor node or a battery-powered handheld instrument, the temperature margin is adequate.","metaTitle":"TPS61092RSAR Boost Converter, 2A Switch, 600kHz, 16-QFN","metaDescription":"Texas Instruments TPS61092RSAR step-up boost converter, 1.8V-5.5V input, fixed 5V output, 2A switch, 600kHz, synchronous rectification, -40°C to 85°C, 16-QFN.","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","Topology":"Boost","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"16-VQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"2A (Switch)","Number of Outputs":"1","Base Product Number":"TPS61092","Output Configuration":"Positive","Frequency - Switching":"600kHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"1.8V","Voltage - Output (Max)":"-","Supplier Device Package":"16-QFN (4x4)","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.7200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9ae6e24c35332339c3f15d0d3223cdfb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61092RSAR/alternatives.json"},"ai":{"faq":[{"question":"What are the input and output voltage ranges of TPS61092RSAR?","answer":"The input voltage range is 1.8V minimum to 5.5V maximum.
