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.
