Description

General part information

TPS54678 Series

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 component 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.

TPS54678 provides accurate regulation for a variety of loads with an accurate ±1% voltage reference (VREF) over temperature.
