With a suitable external N-channel FET and proper thermal management, currents of several amps are achievable. The 2MHz switching frequency limits practical output current to around 3-5 A in most designs due to inductor saturation and MOSFET dissipation."},{"question":"Is MAX16820ATT+T RoHS compliant?","answer":"Yes, the MAX16820ATT+T is ROHS3 compliant."},{"question":"What is the closest pin-compatible alternative to MAX16820ATT+T?","answer":"The evidence does not list a direct pin-compatible second source or alternative. Within the Maxim LED driver controller family, the MAX16820 is the base part; the ATT+T suffix indicates the 6-TDFN package and tape-and-reel. For a drop-in replacement, verify the pinout and switching frequency against other Maxim LED controllers in the same package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/MAX16820ATTT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/MAX16820ATTT when reusing this data.
