Description

General part information

TPS54618-Q1 Series

The TPS54618-Q1 device is a full-featured 6-V, 6-A, synchronous step-down current-mode converter with two integrated MOSFETs.

The TPS54618-Q1 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.

The TPS54618-Q1 provides accurate regulation for a variety of loads with an accurate ±1% voltage reference (VREF) over temperature.
