TPS54218 Overview
TheTPS54218 device is a full-featured, 6-V, 2-A, synchronous, step-down current-mode converter with two integrated MOSFETs. The TPS54218 device 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 device footprint with a small, 3-mm × 3-mm, thermallyenhanced QFN...
