TPS54418 Description
TheTPS54418 device is a full-featured, 6-V, 4-A, synchronous, step-down current-mode converter with two integrated MOSFETs. The TPS54418 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 x 3 mm, thermally enhanced, QFN...
