FEATURES  
DESCRIPTION  
The TPS54388-Q1 device is a full featured 6 V, 3 A,  
synchronous step down current mode converter with  
two integrated MOSFETs.  
2
Qualified for Automotive Applications  
Two 12-m(typical) MOSFETs for High  
Efficiency at 3-A Loads  
The TPS54388-Q1 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.  
200 kHz to 2 MHz Switching Frequency  
0.8 V ± 1% Voltage Reference Over  
Temperature (–40°C to 150°C)  
Synchronizes to External Clock  
Adjustable Slow Start/Sequencing  
UV and OV Power Good Output  
The TPS54388-Q1 provides accurate regulation for a  
variety of loads with an accurate ±1% Voltage  
Reference (VREF) over temperature.  
–40°C to 150°C Operating Junction  
Temperature Range  
Thermally Enhanced 3mm × 3mm 16-pin QFN  
Pin Compatible to TPS54418  
Efficiency is maximized through the integrated 12 m  
MOSFETs and 515 μA typical supply current. Using  
the enable pin, shutdown supply current is reduced to  
5.5 µA by entering a shutdown mode.  
APPLICATIONS  
Low-Voltage, High-Density Power Systems  
Under voltage lockout is internally set at 2.45 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.  
Point of Load Regulation for High Performance  
DSPs, FPGAs, ASICs and Microprocessors  
Broadband, Networking and Optical  
Communications Infrastructure  
Frequency fold back and thermal shutdown protects  
the device during an over-current condition.
