FEATURES  
DESCRIPTION  
The TPS51317 is a fully integrated synchronous buck  
regulator employing D-CAP+mode architechture. It  
is used for 3.3-V and 5-V step-down systems where  
space is a consideration, high-performance and  
optimized component count are required. The  
TPS51317 features four switching frequency settings  
(up to 1.5 MHz), synchronous operation in SKIP,  
droop support, external tracking support, pre-bias  
startup, output soft discharge, integrated bootstrap  
switch, power good function, enable function and  
complete protection functions, and both output  
ceramic and SP/POS capacitor support. It supports  
supply and conversion voltages up to 6.0 V, and  
output voltages adjustable from 0.6 V to 2.0V. The  
TPS51317 is available in the 3.5 mm × 4 mm 20-pin  
QFN package (Green RoHs compliant and Pb free)  
and is specified from -40°C to 85°C.
