Fixed 3.3 V rail, 6 A continuous, 2 MHz switching
The TPS62182YZFT is a fixed 3.3 V output step-down buck converter from Texas Instruments, rated for 6 A continuous output current. Switching at 2 MHz, it keeps the inductor small while maintaining reasonable output ripple for a point-of-load rail. The input range spans 4 V to 15 V, so it handles 5 V and 12 V intermediate buses cleanly. The synchronous rectifier is integrated, which keeps the external BOM to the inductor, input/output caps, and a few passives. No external Schottky diode needed.
Package and thermal: 24-bump DSBGA
Housed in a 24-bump DSBGA (24-UFBGA) package, the TPS62182YZFT is a wafer-level chip-scale package with 0.50 mm pitch. For ambient temperatures above 85°C, derate the output current per the datasheet thermal curves.
The part is ROHS3 compliant.
