The 3.4V minimum input means it can run from a 5V rail or a 3-cell Li-Ion pack. ## Switching frequency — inductor size vs efficiency The switching frequency spans 200kHz to 3MHz. ## Package and thermal — the exposed pad is not optional The 28-TSSOP exposed pad (EP) package requires a thermal land on the PCB. Solder the pad to a copper plane — the datasheet recommends multiple vias to an inner-layer ground plane. Without that thermal path, the junction temperature rises quickly at 2.5A output. The -40°C to 125°C junction rating is real only if the board pulls heat away. In a sealed enclosure with no airflow, derate the output current or add forced air. ## Lifecycle and compliance — no LTB worry It is ROHS3 compliant, so it meets the current EU restriction directive. The #PBF suffix indicates lead-free (Pb-free) finish. No known successor or second-source alternate from the manufacturer; the part is sole-sourced from Analog Devices.","metaTitle":"LT8616EFE#PBF Dual Buck Regulator, 42V Input","metaDescription":"LT8616EFE#PBF dual step-down buck regulator from Analog Devices. 42V max input, 1.5A and 2.5A outputs, adjustable output down to 0.79V.","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":"28-TSSOP (0.173\\\", 4.40mm Width) Exposed Pad","lifecycle_stage":"eol_hot","Current - Output":"1.5A, 2.5A","Number of Outputs":"2","Output Configuration":"Positive","Frequency - Switching":"200kHz ~ 3MHz","Operating Temperature":"-40°C ~ 125°C (TJ)","Synchronous Rectifier":"Yes","Voltage - Input (Max)":"42V","Voltage - Input (Min)":"3.4V","Voltage - Output (Max)":"41.8V","Supplier Device Package":"28-TSSOP-EP","Voltage - Output (Min/Fixed)":"0.79V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$11.14","stockQuantity":0,"priceTiers":[{"qty":1,"price":"$11.14000","currency":"USD"},{"qty":10,"price":"$10.23400","currency":"USD"},{"qty":25,"price":"$9.80960","currency":"USD"},{"qty":100,"price":"$8.64310","currency":"USD"},{"qty":250,"price":"$8.21888","currency":"USD"},{"qty":500,"price":"$7.68862","currency":"USD"},{"qty":1000,"price":"$7.05232","currency":"USD"}]},"links":{"datasheetUrl":"https://cdn.icboms.com/4cb489c196253db4f68cfba16e328e54.pdf","sourceUrl":null},"ai":{"faq":[{"question":"What is the equivalent of LT8616EFE#PBF?","answer":"There is no official second-source or pin-compatible equivalent from another manufacturer.
