It integrates the high-side and low-side switches with internal compensation, reducing external component count to an inductor, a few capacitors, and feedback resistors. The adjustable output is set from 0.97 V up to 12 V. AEC-Q100 qualification and a junction temperature range of -40°C to 125°C make it a direct fit for automotive ECU, ADAS, and infotainment power supplies where board space is tight and thermal performance under hood matters. ## 8 A output and thermal management in the 32-LQFN package Rated for 8 A continuous output, the LT8646SIV#WPBF uses a 32-lead LQFN (6 mm x 4 mm) with an exposed pad. The synchronous rectifier reduces dropout and improves efficiency at high step-down ratios. ## Lifecycle and compliance The LT8646SIV#WPBF carries an Active lifecycle status with ROHS3 compliance. AEC-Q100 qualification is confirmed, supporting PPAP submissions for automotive programs.","metaTitle":"LT8646SIV#WPBF Silent Switcher®2 Buck Regulator, 8 A","metaDescription":"LT8646SIV#WPBF is an Analog Devices Silent Switcher®2 step-down regulator, 8 A output, 3.4 V to 65 V input, AEC-Q100 qualified, -40°C to 125°C.","metaKeywords":null},"attributes":{"series":"Silent Switcher®2","packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Analog & Data Acquisition"],"specifications":{"Grade":"Automotive","Series":"Silent Switcher®2","Package":"Tray","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Qualification":"AEC-Q100","Package / Case":"32-TFQFN Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"8A","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"200kHz ~ 2.2MHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"65V","Voltage - Input (Min)":"3.4V","Voltage - Output (Max)":"12V","Supplier Device Package":"32-LQFN (6x4)","Voltage - Output (Min/Fixed)":"0.97V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$16.97","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$16.97000","currency":"USD"},{"qty":10,"price":"$15.59400","currency":"USD"},{"qty":25,"price":"$14.94800","currency":"USD"},{"qty":80,"price":"$13.17038","currency":"USD"},{"qty":230,"price":"$12.52400","currency":"USD"},{"qty":490,"price":"$11.71600","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/a21774c7466dad9f0d34229b5d72708d.pdf","sourceUrl":null},"ai":{"faq":[{"question":"Is LT8646SIV#WPBF AEC-Q100 qualified?","answer":"Yes, the LT8646SIV#WPBF is AEC-Q100 qualified, making it suitable for automotive-grade applications requiring PPAP support."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/analog-devices/LT8646SIVWPBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/analog-devices/LT8646SIVWPBF when reusing this data.
