General 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 component 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 package.

The TPS54418 device provides accurate regulation for a variety of loads with an accurate ±1% voltage reference (VREF) over temperature.

Key Features

  • 1 Two, 30-mΩ (typical) MOSFETs for HighEfficiency at 4-A loads.
