TPS54519 Step-Down Converter

Texas Instruments' 2.95 V to 6 V input, 5 A synchronous step-down converter

Texas Instruments TPS54519 Step-Down Converter Texas Instruments' 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 a small 3 mm x 3 mm thermally enhanced QFN package.   TPS54519 Datasheet
