Product details

Buck regulator with 1.5 A output and 1 MHz switching

The Texas Instruments TPS62112RSAR is a synchronous step-down (buck) regulator delivering a fixed 5 V output at up to 1.5 A from a 3.1 V to 17 V input rail.

Synchronous rectification for efficiency

The integrated synchronous rectifier replaces the external Schottky diode, improving efficiency across the load range — especially at light loads where a diode's forward drop would dominate losses. The positive output configuration and single-output topology simplify the BOM for a dedicated 5 V rail.
