Texas Instruments  TPS54719RTER

The TPS54719 device is a full featured 6 V, 7 A, synchronous step down current mode converter with two integrated MOSFETs.

The TPS54719 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 x 3mm thermally enhanced QFN package.

The TPS54719 provides accurate regulation for a variety of loads with an accurate ±1.5% Voltage Reference (VREF) over temperature.

Efficiency is maximized through the integrated 30 mΩ MOSFETs and 455µA typical supply current. Using the enable pin, shutdown supply current is reduced to 1 µA by entering a shutdown mode.

Under voltage lockout is internally set at 2.4 V, but can be increased by programming the threshold with a resistor network on the enable pin. The output voltage startup ramp is controlled by the slow start pin. An open drain power good signal indicates the output is within 93% to 108% of its nominal voltage.

Frequency fold back and thermal shutdown protects the device during an overcurrent condition.

The TPS54719 is supported in the Webench™ Software Tool at
