Product Summary

The TPS54418RTER is a full featured 6 V, 4 A, synchronous step down current mode converter with two integrated MOSFETs. The TPS54418RTER 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 3mm x 3mm thermally enhanced QFN package.
