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 www.ti.com/webench.
