The adjustable output is set via an external resistor divider from a 1.265V reference up to 20V. ## Switching frequency and thermal design At higher frequencies the external inductor and output capacitor shrink, but the internal FET switching losses rise — the 2A output ceiling is derated above 1MHz in a compact layout. Without adequate thermal vias under the pad, the regulator thermally limits before reaching 2A in a 70°C ambient.","metaTitle":"LT3684EMSE#PBF Buck Regulator, 2A, 3.6-34V, 10-MSOP-EP","metaDescription":"Analog Devices LT3684EMSE#PBF step-down buck regulator, 2A output, 3.6-34V input range, adjustable output from 1.265V to 20V, 300kHz-3MHz switching frequency","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"10-TFSOP, 10-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"2A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"300kHz ~ 3MHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"No","Voltage - Input (Max)":"34V","Voltage - Input (Min)":"3.6V","Voltage - Output (Max)":"20V","Supplier Device Package":"10-MSOP-EP","Voltage - Output (Min/Fixed)":"1.265V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.8","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$8.80000","currency":"USD"},{"qty":10,"price":"$7.94800","currency":"USD"},{"qty":50,"price":"$7.57800","currency":"USD"},{"qty":100,"price":"$6.57990","currency":"USD"},{"qty":250,"price":"$6.28424","currency":"USD"},{"qty":500,"price":"$5.72972","currency":"USD"},{"qty":1000,"price":"$4.99041","currency":"USD"}]},"links":{"datasheetUrl":null,"sourceUrl":null},"ai":{"faq":[{"question":"What package does LT3684EMSE#PBF come in?","answer":"It is supplied in a 10-lead MSOP with an exposed pad (10-MSOP-EP), 3.00mm body width."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT3684EMSEPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT3684EMSEPBF when reusing this data.
