Product details

Automotive-grade 5V buck for 12V/24V rails

The Maxim MAX16903RAUE50/V+ is a fixed 5V output, 1A step-down (buck) switching regulator built for automotive and industrial environments. It belongs to the Automotive, AEC-Q100 qualified series, meaning it has passed the stress tests required for under-hood and chassis-domain electronics — temperature cycling, high-temperature operating life, and ESD robustness. An integrated synchronous rectifier eliminates the external Schottky diode that older nonsynchronous bucks require — one fewer BOM line, one fewer soldered joint, and better efficiency at light loads.

Package and thermal design

Package is 16-TSSOP-EP. Operating temperature range is -40°C to 125°C. Mounting type is surface mount.

Sourcing and lifecycle

ROHS3 compliant, so it passes the EU RoHS exemption list for automotive.

Frequently asked questions

Does the MAX16903RAUE50/V+ require an external Schottky diode?

No. The part integrates a synchronous rectifier, so no external Schottky diode is needed. This saves a BOM line and improves light-load efficiency compared to nonsynchronous bucks.

Is the MAX16903RAUE50/V+ RoHS compliant?

Yes, it is ROHS3 compliant.
