The TPS62822DLCT is a 2 A continuous-output synchronous buck regulator from Texas Instruments, switching at 2.2 MHz. That switching frequency is the key design lever: it lets you use a small, low-profile inductor — typically a 1 µH to 2.2 µH chip inductor in a 2012 or 2520 footprint — which keeps the power stage compact on a space-constrained board. Output is adjustable from 0.6 V to 4 V, so it covers common core and I/O rails: 1.2 V, 1.8 V, 3.3 V.
