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.
