Automotive buck regulator with AEC-Q100 grade qualification
The MAX16935SAUE/V+T is an automotive-grade step-down buck regulator from Analog Devices, qualified to AEC-Q100 — this is not a 'capable' industrial part; it carries the documented reliability and PPAP traceability that an OEM auditor expects for underhood or cabin electronics. Rated for 3.5A continuous output with an input range from 3.5V to 36V, it covers the full automotive battery envelope including cold-crank dips down to 3.5V and load-dump transients up to 36V without requiring an external clamp. Output is adjustable from 1V up to 10V, with a fixed 5V option available — the adjustable/fixed designation means the same BOM line can serve multiple rail voltages by changing the feedback resistor divider.
16-TSSOP-EP package and thermal management for 3.5A
Surface-mount assembly with Tape & Reel (TR) or Cut Tape (CT) packaging options; the TR variant is the standard for automated pick-and-place in production volumes.
Switching frequency flexibility and non-synchronous design
This range gives the power designer a trade-off knob for the specific automotive load profile. No synchronous rectifier is integrated, meaning the low-side switch is an external Schottky diode. This adds a component but simplifies the layout and avoids the shoot-through risk that synchronous designs face at high input voltages.
Active production with full compliance documentation
ROHS3 compliant, meeting the latest EU restriction requirements. No lead, mercury, cadmium, or other restricted substances in the package or die attach.
