The fixed 3.3 V output at 1 A covers the common MCU, FPGA, or sensor rail without external feedback resistors, saving two components and a placement step. ## Input range and operating envelope The input range runs from 2.3 V to 6 V, so it handles a single Li-Ion cell (3.0 V–4.2 V) or a regulated 5 V bus without a pre-regulator — typical for portable and embedded systems. ## Synchronous rectifier and package","metaTitle":"TPS62291DRVR Buck Regulator 3.3V 1A 6-WSON - TI","metaDescription":"Texas Instruments TPS62291DRVR step-down (buck) regulator, fixed 3.3V output, 1A, 2.25MHz switching, 6-WSON (2x2) package.
