RT9991
Power Management IC for SSD
General Description
The RT9991 is a 3-CH PMIC for SSD (Solid-State Drive).
It integrates 3 synchronous buck converters and one voltage detector.
The RT9991 provides 3 independent enable pins for sequence control and auto discharge when powered off on the power line of a NAND Flash.
The frequency can be up to 1.
5MHz for Buck 1and Buck 2, and up to 2MHz for Buck 3, hence allowing the use of smaller sized inductors to meet the space and height limit in handheld applications.
To maximize power utilization, the RT9991 is designed with extremely low quiescent current.
The buck converter can consume down to 70μA when operating in standby mode.
The RT9991 is av...
