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.
Both parts are from the same TPS6282x family and share the same pinout and 8-VSON-HR package. The TPS62822DLCT is the 2 A output variant; the TPS62820 is the 1 A variant. If your load requires up to 2 A, the TPS62822DLCT is a drop-in replacement. If your load is under 1 A, the TPS62820 may be a lower-cost option, but the TPS62822DLCT will also work — just with more current headroom.
