TPS51363
General 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. The feature set includes switching frequency of 400 kHz and 800
kHz. Programmable soft-start time with an external capacitor. auto skip, pre-bias startup, integrated bootstrap
switch, power good, enable and a full suite of fault protection schemes, including OCL, UVP, OVP, 5-V UVLO
and thermal shutdown. It is packaged in 3.5 mm × 4.5 mm, 0.4-mm pitch, 28-pin QFN (RVE), and specified
from -10°C to 85°C.
