Internal synchronous rectification eliminates the external catch diode, saving a component and a placement site on the board. The 600 mA output is derated above 70°C ambient depending on the board's copper area — a four-layer board with a solid ground plane carries the full current rating across the temperature band.","metaTitle":"LTC3448EMS8E#PBF Buck Regulator, 600mA, 8-MSOP-EP","metaDescription":"Analog Devices LTC3448EMS8E#PBF step-down buck regulator, 600mA output, 2.5-5.5V input, 1.5-2.25MHz switching, adjustable output, 8-MSOP-EP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":"ROHS3 Compliant","productStatus":"Active","categoryPath":["Discrete Semiconductors"],"specifications":{"Package":"Tube","Function":"Step-Down","Topology":"Buck","Output Type":"Adjustable","Mounting Type":"Surface Mount","Package / Case":"8-TSSOP, 8-MSOP (0.118\\\", 3.00mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"600mA","Number of Outputs":"1","Output Configuration":"Positive","Frequency - Switching":"1.5MHz ~ 2.25MHz","Operating Temperature":"-40°C ~ 85°C (TA)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"5.5V","Voltage - Input (Min)":"2.5V","Voltage - Output (Max)":"5.2V","Supplier Device Package":"8-MSOP-EP","Voltage - Output (Min/Fixed)":"0.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$6.97","priceTiers":[{"qty":1,"price":"$6.97000","currency":"USD"},{"qty":10,"price":"$6.25700","currency":"USD"},{"qty":25,"price":"$5.91480","currency":"USD"},{"qty":100,"price":"$5.12620","currency":"USD"},{"qty":250,"price":"$4.86328","currency":"USD"},{"qty":500,"price":"$4.36380","currency":"USD"},{"qty":1000,"price":"$3.72000","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/6cd289f49ce81edfa69afeeef9fc75cc.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LTC3448EMS8E%23PBF/alternatives.json"},"ai":{"faq":[{"question":"How can I order LTC3448EMS8E#PBF or check its availability?","answer":"The LTC3448EMS8E#PBF is an active Analog Devices part."},{"question":"Does LTC3448EMS8E#PBF replace LT8631HFE#PBF in the same board?","answer":"No. The LT8631HFE#PBF is a 1 A-rated buck in a different package (16-TSSOP exposed pad) with a 3 V minimum input and 150°C junction temperature rating.
