TPS54678 Overview
TPS54678 device is a full-featured 6-V, 6-A, synchronous step-down current mode converter with two integrated MOSFETs. TPS54678 enables small designs by integrating the MOSFETs, implementing current mode control to reduce external ponent count, reducing inductor size by enabling up to 2-MHz switching frequency, and minimizing the IC footprint with a small 3-mm × 3-mm thermally enhanced WQFN package.
