It is AEC-Q100 qualified and rated for -40°C to 150°C junction temperature. ## Switching frequency — inductor sizing trade-off The LM5141QURGERQ1 lets you set the switching frequency to either 440 kHz or 2.2 MHz. At 440 kHz the efficiency peak is higher and the MOSFET switching losses lower, but the inductor needs to be physically larger. At 2.2 MHz the inductor shrinks to a small footprint — good for space-constrained layouts — though the gate-drive losses go up. The same controller covers both cases via a single resistor change, which is handy if you are qualifying one design across multiple power-stage sizes. ## Package and mounting — 24-VQFN with exposed pad The part comes in a 24-VQFN exposed-pad package (4x4 mm body). The exposed pad must be soldered to a copper plane on the PCB.","metaTitle":"LM5141QURGERQ1 Automotive Buck Controller, 65V Input, 2.2MHz","metaDescription":"TI LM5141QURGERQ1 automotive-grade synchronous buck controller. 3.8V–65V input, 440kHz/2.2MHz switching, AEC-Q100, 24-VQFN.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"Not applicable","productStatus":"Active","categoryPath":["DC-DC Power Modules"],"specifications":{"Grade":"Automotive","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Clock Sync":"Yes","Output Type":"Transistor Driver","Mounting Type":"Surface Mount","Output Phases":"1","Qualification":"AEC-Q100","Package / Case":"24-VFQFN Exposed Pad","lifecycle_stage":"eol_hot","Control Features":"Current Limit, Enable, Frequency Control, Power Good, Soft Start","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"440kHz, 2.2MHz","Operating Temperature":"-40°C ~ 150°C (TJ)","Synchronous Rectifier":"Yes","Supplier Device Package":"24-VQFN (4x4)","Voltage - Supply (Vcc/Vdd)":"3.8V ~ 65V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$5.81","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$5.81000","currency":"USD"},{"qty":10,"price":"$5.21600","currency":"USD"},{"qty":25,"price":"$4.93120","currency":"USD"},{"qty":100,"price":"$4.27380","currency":"USD"},{"qty":250,"price":"$4.05464","currency":"USD"},{"qty":500,"price":"$3.63822","currency":"USD"},{"qty":1000,"price":"$3.06838","currency":"USD"},{"qty":3000,"price":"$2.91496","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/83dd1bb21575b48ec12d571206344236.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LM5141QURGERQ1 AEC-Q100 qualified?","answer":"Yes, the part carries AEC-Q100 qualification and an automotive grade rating, suitable for under-hood and chassis-domain applications."},{"question":"Does LM5141QURGERQ1 support clock synchronization?","answer":"Yes — clock synchronization is supported, allowing the controller to lock to an external clock for noise management in multi-rail systems."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LM5141QURGERQ1","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LM5141QURGERQ1 when reusing this data.
