It delivers up to 3.5A from a 3.5V to 36V input rail, covering the full 12V battery range from cold-crank at 4.5V through load-dump transients that hit 36V. The output is adjustable from 1V up to 10V, with a fixed 5V option available — useful for powering 5V logic rails or sensor supplies directly without an external divider. The switching frequency spans 220kHz to 2.2MHz, letting you trade inductor size against efficiency: lower frequency for better efficiency in tight thermal budgets, higher frequency for smaller magnetics in space-constrained ECU layouts. ## Non-synchronous topology — plan for the external Schottky This is a non-synchronous buck (no internal synchronous rectifier), so the design requires an external Schottky catch diode. The diode's forward voltage and thermal rating directly affect efficiency at high duty cycles — a 40V, 5A Schottky with Vf under 0.5V is typical for this current class. The 125°C junction temperature rating matches the under-hood ambient of an automotive ECU. At 85°C ambient, the 3.5A output derates — the 5x5mm 16-TQFN exposed-pad package relies on the PCB copper pour for thermal dissipation. The datasheet's thermal impedance figure assumes a 2oz copper, 4-layer board with thermal vias under the pad. ROHS3 compliant, so no lead-process exemption issues for European automotive OEMs. The tube packaging is standard for prototype and low-volume builds; for production reels, confirm the tape-and-reel order code variant with your distributor. ## Active production — single-source reality The -40°C to +125°C operating range covers engine bay and cabin applications.","metaTitle":"MAX16935SATE/V+ Buck Converter, 3.5A, 36V Input, AEC-Q100","metaDescription":"Active-production MAX16935SATE/V+ step-down converter from Analog Devices. 3.5A output, 3.5V-36V input, AEC-Q100 qualified.
