The TPS62132RGTR: The DCS-Control topology keeps the switching frequency at 2.5 MHz, which lets the output filter use small inductors and ceramics — a common choice for space-constrained 3.3 V rails in industrial and telecom boards.
At 2.5 MHz, the typical inductor value drops to the 1 µH to 2.2 µH range, which fits a 2.0 mm or 2.5 mm footprint.
The TPS62133RGTR is the same 3 A synchronous buck in the same 3x3 mm QFN package, but its fixed output is 5 V instead of 3.3 V. The pinout, switching frequency, and input range are identical — the only difference is the output voltage set point.
