FEATURES  
DESCRIPTION  
2
Two 45-m(typical) MOSFETs for High  
The TPS54319 device is a full featured 6 V, 3 A,  
synchronous step down current mode converter with  
two integrated MOSFETs.  
Efficiency at 3-A Loads  
300kHz to 2MHz Switching Frequency  
0.8 V ± 3.0% Voltage Reference Over  
Temperature (0°C to 85°C)  
The TPS54319 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.  
Synchronizes to External Clock  
Adjustable Slow Start/Sequencing  
UV and OV Power Good Output  
–40°C to 150°C Operating Junction  
Temperature Range  
The TPS54319 provides accurate regulation for a  
variety of loads with an accurate ±3.0% Voltage  
Reference (VREF) over temperature.  
Thermally Enhanced 3mm × 3mm 16-pin QFN  
Pin Compatible to TPS54318  
Efficiency is maximized through the integrated 45m  
MOSFETs and 360mA typical supply current. Using  
the enable pin, shutdown supply current is reduced to  
2 µA by entering a shutdown mode.  
APPLICATIONS  
Low-Voltage, High-Density Power Systems  
Point-of-Load Regulation for Consumer  
Applications such as Set Top Boxes, LCD  
Displays, CPE Equipment  
Under voltage lockout is internally set at 2.6 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 107% of its nominal voltage.  
SIMPLIFIED SCHEMATIC
