The 4 V minimum input covers 5 V regulated rails directly; the 34 V maximum covers 24 V industrial bus and 12 V automotive systems with headroom for load-dump transients. ## 200 kHz fixed-frequency — inductor size vs EMI trade-off Switching at 200 kHz keeps the fundamental switching noise below the AM broadcast band, simplifying input filter design for noise-sensitive loads. The fixed 200 kHz rate allows a 47-100 µH inductor in the standard 8-SOIC layout — small enough for a compact board, large enough to keep ripple current below 30 % of the 2 A load. No synchronous rectifier is integrated — an external Schottky diode (e.g., 3 A, 40 V) is required for the catch diode, which adds a cent in BOM but simplifies the output stage for low-duty-cycle designs. ## -40 to 125 °C junction — industrial and automotive temperature grade The 8-SOIC package (0.154\" wide, 3.90 mm body) has no exposed thermal pad — the primary heat path is through the copper traces and PCB planes, so a 2-oz copper pour on the top layer is recommended for full 2 A output at high ambient. Surface-mount assembly with tube packaging — the 8-SOIC footprint is standard across pick-and-place lines; tube handling is fine for prototype runs or low-volume production. ## Active production — no EOL risk for current BOMs ROHS3 compliant — no substance restrictions for EU, UKCA, or global markets; no exemption expiry to track.","metaTitle":"MIC4682YM Buck Regulator, 2A, 8-SOIC, Active","metaDescription":"MIC4682YM step-down regulator from Microchip Technology, 2 A output, 4-34 V input, adjustable output, 8-SOIC, active production, ROHS3 compliant.","metaKeywords":null},"attributes":{"series":"SuperSwitcher™","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Series":"SuperSwitcher™","Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Output":"2A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"200kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"No","Voltage - Input (Max)":"34V","Voltage - Input (Min)":"4V","Voltage - Output (Max)":"32.3V","Supplier Device Package":"8-SOIC","Voltage - Output (Min/Fixed)":"1.23V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.93","priceTiers":[{"qty":1,"price":"$4.93000","currency":"USD"},{"qty":25,"price":"$4.10000","currency":"USD"},{"qty":100,"price":"$3.75000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/83a7000cf078e26734ac70b389340650.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MIC4682YM/alternatives.json"},"ai":{"faq":[],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/MIC4682YM","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/MIC4682YM when reusing this data.
