DESCRIPTION  
The TPS53317 is a fully-integrated,synchronous buck  
regulator employing D-CAP+technology. It is used  
for rail step-downs from 1 V to 6 V where space is a  
consideration, and an optimized component count is  
required.  
The TPS53317 features two switching frequency  
settings (600 kHz and 1 MHz), synchronous operation  
in skip (low ripple) mode, integrated droop support,  
external tracking support, pre-bias startup, output soft  
discharge, integrated bootstrap switch, power good  
function, EN/Input UVLO protection, and both output  
ceramic and SP/POS/AL capacitor support. It  
supports supply and conversion voltages up to 6.0 V,  
and output voltages adjustable from 0.6 V to 2.0 V. It  
also provides external tracking support.  
The TPS53317 is available in the 3.5 mm by 4 mm,  
20-pin QFN package (Green RoHs compliant and Pb  
free) with TI proprietary Integrated MOSFET and  
packaging technology and is specified from -40°C to  
85°C.
