Product Summary

The TPS54218RTER is a full featured 6 V, 2 A, synchronous step down current mode converter with two integrated MOSFETs. The TPS54218RTER 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 × 3mm thermally enhanced QFN package. The applications of the TPS54218RTER include Low-Voltage, High-Density Power Systems, Point of Load Regulation for High Performance DSPs, FPGAs, ASICs and Microprocessors, Broadband, Networking and Optical Communications Infrastructure.
