It is ROHS3 compliant. For an automotive program that runs five to ten years, this part is a safe selection from a continuity standpoint. The AEC-Q100 qualification means the OEM PPAP package is available through the standard TI documentation channel.","metaTitle":"LM3489MM/NOPB Buck Controller, AEC-Q100, 4.5V-35V, 1MHz","metaDescription":"TI LM3489MM/NOPB automotive-grade buck controller in 8-VSSOP.

The operating temperature range of -40°C to 125°C covers under-hood and engine-bay environments. The OEM auditor will expect AEC-Q grade documentation and PPAP evidence, which TI provides through its standard qualification package."},{"question":"Can LM3489MM/NOPB be used for a 5V output?","answer":"Yes. With a 4.5V minimum input, the LM3489MM/NOPB can generate a 5V output from a 6V to 35V rail. At 100% duty cycle, it can hold regulation even when the input drops to 5.5V, which is useful in battery-powered or cranking conditions. The external MOSFET and Schottky diode must be selected for the 5V output current and the maximum input voltage."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM3489MM-NOPB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM3489MM-NOPB when reusing this data.
