The TPS62133RGTR is a fixed 5 V output, 3 A continuous buck regulator from the Texas Instruments DCS-Control™ family. The 3 A rating is the continuous output current at the nominal input range; the part delivers this without an external Schottky because the synchronous rectifier is integrated. For a BOM line calling for a 5 V rail at 3 A, this part fits directly — no resistor divider needed for the output set point. The 2.5 MHz switching frequency allows the use of small-value inductors and ceramic output capacitors, shrinking the PCB footprint. The trade-off is higher switching losses than a lower-frequency part; at light loads the DCS-Control architecture maintains efficiency by modulating the on-time.
