The 400 kHz fixed switching frequency keeps the inductor in the 10 µH to 47 µH range, balancing ripple and component size. ## Synchronous rectifier saves a diode The built-in synchronous rectifier eliminates the external Schottky catch diode that a non-synchronous buck would need. That saves about 0.5 V of forward drop at 1 A and removes one component from the BOM. The trade-off is that the low-side FET stays on during light load, so efficiency at sub-10 mA loads is lower than a diode-rectified part — plan for a preload or pulse-skip mode if the design spends time in standby. ## 125 °C junction — industrial, not 150 °C automotive It is not rated for 150 °C junction like some AEC-Q100 automotive parts (e.g., the LMS3655MQURNLRQ1), so if the ambient around the regulator exceeds 105 °C with 1 A load, the thermal margin narrows. The 8-SO PowerPad package needs a solid via stitch to the ground plane to keep the junction below 125 °C at full load.","metaTitle":"LMR36510FADDAR SIMPLE SWITCHER Buck Regulator","metaDescription":"Texas Instruments LMR36510FADDAR SIMPLE SWITCHER step-down regulator: 4.2 V to 65 V input, 1 A output, synchronous rectification, 400 kHz switching, -40°C to","metaKeywords":null},"attributes":{"series":"SIMPLE SWITCHER®","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Logic ICs"],"specifications":{"Series":"SIMPLE SWITCHER®","Package":"Tape & Reel (TR); Cut Tape (CT)","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-PowerSOIC (0.154\\\", 3.90mm Width)","lifecycle_stage":"eol_hot","Current - Output":"1A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"400kHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"65V","Voltage - Input (Min)":"4.2V","Voltage - Output (Max)":"61.75V","Supplier Device Package":"8-SO PowerPad","Voltage - Output (Min/Fixed)":"1V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.23","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$2.23000","currency":"USD"},{"qty":10,"price":"$2.00500","currency":"USD"},{"qty":25,"price":"$1.89120","currency":"USD"},{"qty":100,"price":"$1.61130","currency":"USD"},{"qty":250,"price":"$1.51296","currency":"USD"},{"qty":500,"price":"$1.32386","currency":"USD"},{"qty":1000,"price":"$1.09691","currency":"USD"},{"qty":2500,"price":"$1.02126","currency":"USD"},{"qty":5000,"price":"$0.98344","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/cf894908ed2e347d70d873ba7dcf71b3.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Does LMR36510FADDAR require an external synchronous rectifier?","answer":"No. The LMR36510FADDAR has an integrated synchronous rectifier, so no external Schottky diode is needed for the catch diode function."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/LMR36510FADDAR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/LMR36510FADDAR when reusing this data.
