Product details

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.

Input range and temperature grade — where it fits and where it does not

The input voltage range is 3 V to 17 V.

Package and thermal — 16-VQFN (3x3) with exposed pad

The TPS62133RGTR is supplied in a 16-VQFN (3x3) exposed pad package.

The part is ROHS3 compliant.

Frequently asked questions

What is the switching frequency of TPS62133RGTR?

The switching frequency is 2.5 MHz. This allows small external components but increases switching losses compared to a 400 kHz part.

Can TPS62133RGTR be used for a 3.3 V output?

No. The output is fixed at 5 V. For a 3.3 V output, use the adjustable version TPS62133A or another fixed 3.3 V variant in the same family.

What are equivalent parts to TPS62133RGTR?

Functional alternatives include the LM53625LQURNLRQ1 (automotive, 2.5 A, 2.1 MHz, fixed 5 V) and LMR33630APCQRNXRQ1 (automotive, 3 A, adjustable output, 2.1 MHz). Both are AEC-Q100 qualified and operate to 125°C junction, but differ in package and output adjustability.
