Switching at 500 kHz, the inductor and output capacitor shrink to a 0805 or smaller footprint — the trade-off is that the switching losses in the FETs start to climb above this frequency, so 500 kHz is the sweet spot for a 1A rail where board space matters more than a few milliwatts of quiescent loss.","metaTitle":"MCP16311T-E/MNY Microchip Step-Down Buck, 1A, 500kHz","metaDescription":"MCP16311T-E/MNY Microchip Technology step-down buck regulator, 1A output, 500kHz switching, adjustable 2-24V, 4.4-30V input, -40 to +125°C, 8-TDFN, ROHS3.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-WFDFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"1A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"500kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"30V","Voltage - Input (Min)":"4.4V","Voltage - Output (Max)":"24V","Supplier Device Package":"8-TDFN (2x3)","Voltage - Output (Min/Fixed)":"2V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.95","priceTiers":[{"qty":1,"price":"$1.95000","currency":"USD"},{"qty":25,"price":"$1.63240","currency":"USD"},{"qty":100,"price":"$1.50000","currency":"USD"},{"qty":3300,"price":"$1.50000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/ed805f15e0b62c714d285e64210c44d7.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/MCP16311T-E%2FMNY/alternatives.json"},"ai":{"faq":[{"question":"What is the output current and switching frequency of the MCP16311T-E/MNY?","answer":"The MCP16311T-E/MNY delivers 1 A continuous output and switches at 500 kHz. The synchronous rectifier keeps efficiency above 85% across most of the load range, so the 1 A rating is real — not a peak number that collapses under thermal stress."},{"question":"What input voltage range does the MCP16311T-E/MNY accept?","answer":"The input range is 4.4 V to 30 V, which means it can run from a 5 V USB supply, a 12 V industrial rail, or a 24 V battery bus without an external pre-regulator. The adjustable output goes from 2 V to 24 V, so a single design can serve multiple rail voltages."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/microchip/MCP16311T-E-MNY","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/microchip/MCP16311T-E-MNY when reusing this data.
