It is designed for battery-powered equipment — think single-cell Li-ion, two- or three-cell alkaline, or USB-powered peripherals that need a clean 5V rail for sensors, logic, or small motors. The 1.8A switch current rating sets the practical output power ceiling: at 5V out, you can draw roughly 900 mA to 1 A continuous before the switch current limit is hit, depending on input voltage and efficiency. ## 600 kHz switching and synchronous rectification Switching at 600 kHz keeps the inductor and output capacitor physically small — a 4.7 µH to 10 µH shielded inductor and a 10 µF ceramic output cap are typical. The synchronous rectifier replaces the usual Schottky catch diode, which improves efficiency at light loads by several percent compared to a non-synchronous boost. For a battery-powered device spending most of its time in standby or low-power mode, that efficiency gain directly extends shelf life or run time between charges. ## Package and thermal layout For a 5V output at 500 mA load from a 3.3V input, the power dissipation is modest, but at higher loads or lower input voltages the thermal pad becomes essential — a layout that skips the thermal vias under the pad will hit the thermal shutdown threshold sooner. For dual-sourcing, a designer would need to evaluate other synchronous boost converters in the same 10-VSON footprint with a fixed 5V output and 1.8A switch rating.","metaTitle":"TPS61026DRCR Boost Converter, 5V Fixed Output, 1.8A Switch","metaDescription":"Texas Instruments TPS61026DRCR step-up boost converter with fixed 5V output, 1.8A switch current, 600kHz switching, synchronous rectification.","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)","Function":"Step-Up","Topology":"Boost","Output Type":"Fixed","Mounting Type":"Surface Mount","Package / Case":"10-VFDFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"1.8A (Switch)","Number of Outputs":"1","Base Product Number":"TPS61026","Output Configuration":"Positive","Frequency - Switching":"600kHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"0.9V","Voltage - Output (Max)":"-","Supplier Device Package":"10-VSON (3x3)","Voltage - Output (Min/Fixed)":"5V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.2345","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6c4beb242ccaaf27834cfb8166337f86.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61026DRCR/alternatives.json"},"ai":{"faq":[{"question":"Is TPS61026DRCR a boost converter?","answer":"Yes, it is a step-up (boost) topology converter.
