For a 3.3 V to 5 V boost at 600 kHz, expect around 1 A output with good layout and a properly sized inductor. Output voltage is adjustable via an external resistor divider from 1.8 V (the minimum fixed output) up to the 5.5 V maximum input rating — the same pin handles feedback and enable sequencing. Synchronous rectification replaces the usual boost diode with a second internal FET, improving efficiency at light loads and eliminating the external Schottky — a real BOM simplification for battery-powered designs. The 16-VQFN package with exposed pad (MSL rating typical for this class) demands a bake before reflow if the moisture-barrier bag is breached — standard floor life is 168 hours at <30°C/60% RH per JEDEC Level 3.","metaTitle":"TPS61090RSARG4 Step-Up Boost Converter, 2A Switch, 600kHz","metaDescription":"Texas Instruments TPS61090RSARG4 step-up boost converter, 1.8V-5.5V input, adjustable output to 5.5V, 2A switch, 600kHz, synchronous rectifier, -40°C to 85°C","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":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"16-VQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"2A (Switch)","Number of Outputs":"1","Base Product Number":"TPS61090","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)":"5.5V","Supplier Device Package":"16-QFN (4x4)","Voltage - Output (Min/Fixed)":"1.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$3.1300","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9ae6e24c35332339c3f15d0d3223cdfb.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS61090RSARG4/alternatives.json"},"ai":{"faq":[{"question":"Can TPS61090RSARG4 be used to boost 3.3V to 5V?","answer":"The 600 kHz switching frequency and synchronous rectification support efficient conversion at this ratio."},{"question":"Is TPS61090RSARG4 RoHS compliant and lead-free?","answer":"The part is listed as RoHS compliant and lead-free per standard Texas Instruments green packaging.
