Description
General part information
TPS54519 Series
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 a small 3mm × 3mm thermally enhanced QFN package.
Efficiency is maximized through the integrated 30mΩ MOSFETs and 350µA typical supply current. Using the enable pin, shutdown supply current is reduced to 2 µA by entering a shutdown mode.
