Output is adjustable from 0.6 V up to 14 V via external feedback resistors, and the synchronous rectifier (internal FET instead of a catch diode) keeps efficiency up at the 5 A load — the scorch mark on a board with a diode-based buck often points to the catch diode failing first. Switching frequency is programmable at 600 kHz, 1 kHz, or 2.2 MHz — the 1 kHz setting is unusual and likely a spread-spectrum or light-load mode; at 2.2 MHz the inductor shrinks but switching losses climb, so the 600 kHz setting is the one to start with on a new layout. ## Sourcing and compliance for the BOM line Listed as Active in production and ROHS3 compliant — no NRND or EOL flag, so it's still a valid design-in choice for new boards.","metaTitle":"BD9F500QUZ-E2 ROHM Step-Down Buck, 5A, 36V Input","metaDescription":"ROHM BD9F500QUZ-E2 step-down buck converter, 5A output, 4.5-36V input, adjustable 0.6-14V, 600kHz/2.2MHz switching, active production, ROHS3 compliant.","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":"16-XFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"5A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"600kHz, 1KHz, 2.2MHz","Operating Temperature":"-40°C ~ 85°C","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"36V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"14V","Supplier Device Package":"VMMP16LZ3030","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$4.45","priceTiers":[{"qty":1,"price":"$4.45000","currency":"USD"},{"qty":10,"price":"$4.00100","currency":"USD"},{"qty":100,"price":"$3.27800","currency":"USD"},{"qty":500,"price":"$2.79054","currency":"USD"},{"qty":1000,"price":"$2.35347","currency":"USD"},{"qty":2500,"price":"$2.23580","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/e2969c327ef6dcad81bc10c7f603035d.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BD9F500QUZ-E2/alternatives.json"},"ai":{"faq":[{"question":"What compliance documentation does ROHM provide for BD9F500QUZ-?","answer":"The part is ROHS3 compliant; no REACH, UL, or IEC documentation is listed in the available record."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/rohm/BD9F500QUZ-E2","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/rohm/BD9F500QUZ-E2 when reusing this data.
