The high switching frequency shrinks the inductor and output capacitor to a few mm² footprint, while the DCS-Control hysteretic architecture delivers load-transient recovery in a few switching cycles without external compensation components. The adjustable output starts at a 0.8 V minimum reference, suiting it for low-voltage core rails in FPGAs, MCUs, and SoCs. ## Switching frequency and loop stability At 2.8 MHz, the switching frequency stays above the AM radio band and keeps ripple well within 10 mVpp with a 1 µH inductor and 22 µF output cap. The DCS-Control scheme combines voltage-mode feedforward and current-mode hysteretic control, giving near-instantaneous response to load steps without the phase-margin headaches of Type-III compensation. ## Package and thermal: 16-VQFN (3x3) The copper area on the bottom layer directly sets RthJA — a 1 in² pour drops it to about 40 °C/W, enough for 3 A at 85 °C ambient with 90% efficiency. ## Synchronous rectification and efficiency The 3 A rating is continuous; peak current limiting protects the inductor and output cap during startup or fault conditions.","metaTitle":"TPS62090RGTT 3A Step-Down Buck Converter, 2.8MHz","metaDescription":"Texas Instruments TPS62090RGTT 3A step-down buck converter with DCS-Control, 2.5V-6V input, adjustable output from 0.8V, 2.8MHz switching, -40°C to 85°C","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"DCS-Control™","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"16-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"3A","Number of Outputs":"1","Base Product Number":"TPS62090","Output Configuration":"Positive","Frequency - Switching":"2.8MHz","Operating Temperature":"-40°C~85°C(TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"6V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"6V","Supplier Device Package":"16-VQFN (3x3)","Voltage - Output (Min/Fixed)":"0.8V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.9400","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/6c4fd071e2f45baba97c8fb176869de4.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS62090RGTT/alternatives.json"},"ai":{"faq":[{"question":"What is the output current of TPS62090RGTT?","answer":"The TPS62090RGTT is rated for a continuous output current of 3 A."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS62090RGTT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS62090RGTT when reusing this data.
