That 65V ceiling means it survives 48V telecom bus transients and 24V industrial supply surges without external clamping — the internal FET's breakdown rating covers the headroom. Output is adjustable from 0.97V up to 64.75V, so it can power a 1.2V core rail or a 48V auxiliary bus from the same regulator. The switching frequency spans 200kHz to 2.2MHz, letting you trade inductor size against efficiency — lower frequency for better efficiency in tight thermal budgets, higher frequency for a smaller footprint. ## 150°C junction — the high-temp envelope Rated for junction temperatures from -40°C to 150°C (TJ), this part sits in the industrial/military temperature band. A 150°C max junction means the silicon itself can handle the self-heating from a 2A load in a warm enclosure — but the board-level derating depends on the 16-MSOP-EP exposed-pad's thermal resistance. Synchronous rectification is built in — the internal low-side FET replaces the external Schottky diode, keeping the efficiency curve above 90% across most of the load range. That matters in a 2A design where the diode conduction loss would otherwise dominate the thermal budget. Lifecycle status is Active per the manufacturer (Analog Devices), and the part carries ROHS3 compliance. The package is Tube (the standard 16-MSOP-EP tray format). If your pick-and-place line is set up for MSOP-EP with exposed pad, the footprint and thermal pad match the 3.00mm-width body. The LT8620IMSE#PBF sibling shares the same 16-MSOP-EP package and pinout but is rated to 125°C junction instead of 150°C — the -H suffix on this part buys the extra 25°C headroom for high-ambient or confined enclosures.","metaTitle":"LT8620HMSE#PBF Buck Regulator, 2A Adjustable, 65V Input","metaDescription":"Analog Devices LT8620HMSE#PBF step-down regulator, 2A output, 65V max input, adjustable output, 200kHz-2.2MHz, -40 to 150°C.

The key difference is the operating temperature range: the -I grade is rated -40°C to 125°C junction, while the -H grade (this part) goes to 150°C. If your thermal analysis stays below 125°C, the -I variant drops in without a board spin."},{"question":"What compliance documentation does Analog Devices provide for LT8620HMSE#PBF?","answer":"The part is ROHS3 compliant.
