Product details

1A automotive buck with 3.3V fixed output

The Texas Instruments TPS628113HQWRWYRQ1 is a synchronous step-down buck converter delivering 1A continuous output at a fixed 3.3V. It operates from a 2.75V to 6V input rail, covering the typical automotive battery range after pre-regulation. Switching frequency is programmable between 1.8MHz and 4MHz, allowing the use of small inductors and ceramic capacitors to fit tight ECU layouts.

AEC-Q100 qualified for under-hood and chassis domains

The 9-VFQFN package with wettable flank (3x2 mm body) supports automated optical inspection of solder joints, a common requirement for automotive production lines.
