The adjustable output voltage range starts at 0.6 V and goes up to 16.2 V, covering the common core, I/O, and auxiliary rails in an automotive ECU or ADAS sensor module. ## Switching frequency flexibility — inductor sizing trade-off At the low end you use a larger inductor but get better efficiency; at the high end the inductor shrinks but switching losses rise. This lets the power-stage designer optimise for board area or thermal budget without changing the regulator IC.","metaTitle":"TPS65400QRGZTQ1 Automotive Quad Buck Regulator, 4A/2A","metaDescription":"Texas Instruments TPS65400QRGZTQ1 automotive-qualified quad-output step-down regulator, 4A/2A per channel, 4.5V–18V input, adjustable output down to 0.6V.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Active","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Texas Instruments","Series":"Automotive, AEC-Q100","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"48-VFQFN Exposed Pad","Product Status":"Active","lifecycle_stage":"eol_hot","Current - Output":"4A, 2A","Number of Outputs":"4","Base Product Number":"TPS65400","Output Configuration":"Positive","Frequency - Switching":"275kHz ~ 2.2MHz","Operating Temperature":"-40°C~125°C(TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"18V","Voltage - Input (Min)":"4.5V","Voltage - Output (Max)":"16.2V","Supplier Device Package":"48-VQFN (7x7)","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$7.9600","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/2c0c1aab79c759cd49f9c3b113247067.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/TPS65400QRGZTQ1/alternatives.json"},"ai":{"faq":[{"question":"Is TPS65400QRGZTQ1 automotive qualified?","answer":"Yes, the TPS65400QRGZTQ1 is listed with series Automotive, AEC-Q100, meaning it is qualified for automotive-grade applications including under-hood and chassis domains."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/TPS65400QRGZTQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/TPS65400QRGZTQ1 when reusing this data.
