Typical applications include portable devices, battery-powered sensors, and single-cell Li-ion or alkaline systems that need a regulated 5 V rail for USB OTG, sensor modules, or small displays. ## Switch current and output power budget The 1.5 A switch current limit is the hard ceiling for the inductor peak current. For a 5 V output from a 3.3 V input, the maximum continuous output current is roughly 0.9 A, assuming 85% efficiency. If your load pulls more, the converter enters current-limit foldback and the output drops. Size the inductor for a 30% ripple current at the maximum input voltage to keep the peak below the switch limit. Synchronous rectification replaces the output Schottky diode with a low-side FET, cutting forward-conduction losses by 3–5% at moderate loads. This matters most when the battery voltage is near the output — the duty cycle is high and the rectifier conduction time is long. ## 600 kHz switching and component selection The 600 kHz switching frequency is a practical middle ground: it allows a 4.7 µH to 10 µH inductor and 10 µF to 22 µF output capacitor in a small footprint, while keeping switching losses low enough for >85% efficiency across most of the load range. The fixed frequency simplifies EMI filtering — the fundamental and its harmonics land predictably. Without adequate thermal vias, the switch current derates above 70°C ambient.","metaTitle":"Texas Instruments TPS61027DRCRSY Step-Up Boost Converter","metaDescription":"Texas Instruments TPS61027DRCRSY boost converter, fixed 5V output, 1.5A switch, 600kHz, synchronous rectification, -40°C to 85°C, 10-VSON.","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":"1.5A (Switch)","Number of Outputs":"1","Base Product Number":"TPS61027","Output Configuration":"Positive","Frequency - Switching":"600kHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6.5V","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":"$1.1610","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/d13cddc1f9c03d5c7ecbbbaf8dfd663b.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61027DRCRSY/alternatives.json"},"ai":{"faq":[{"question":"What is the difference between TPS61027DRCR and TPS61027DRCRSY?","answer":"The TPS61027DRCRSY suffix indicates Tape & Reel packaging.
