FEATURES
DESCRIPTION
•
•
•
The TPS51363 is a high-voltage input, synchronous
converter with integrated FET, based on D-CAP2™
control topology, which enables fast transient
response and supports both POSCAP and all MLCC
output capacitors. TI proprietary FET technology
combined with TI leading-edge package technology
provides the highest density solution for single-output
power rail such as VCCIO and VDDQ for DDR
notebook memory, or any point-of-load (POL) in wide
application.
