General Description
The RT5168 is an integrated solution for SSD power
management IC. This device provides 5 single Buck
voltage regulators (Rail1 to Rail5) and 1 LDO. Among
the 5 voltage regulators, the Rail1, Rail2, Rail3 and
Rail4 can operate either in single phase mode or dual
phase mode. A complete protection mechanism is
also embedded for safe power distribution and the
corresponding fault events can be recorded by the
registers. The RT5168 is available in a UQFN40L.5x5-FC package. The recommended junction
temperature is 0°C to 125°C, and the ambient
temperature is 0°C to 85°C.
