TPS54519 - Texas Instruments

TPS54519 5-A Synchronous Step Down Converter

The TPS54519 device is a full featured 6 V, 5 A, synchronous step down current mode converter with two integrated MOSFETs. The TPS54519 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.
