Overview
RT9996 Power Management IC for SSD General Description The RT9996 is a 2-CH PMIC for SSD (Solid-State Drive).
It integrates synchronous buck converters and one voltage detector.
The RT9996 provides 2 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 2MHz, allowing the use of smaller sized inductors to meet the space and height limit in handheld applications.
To maximize power utilization, the RT9996 is designed with extremely low quiescent current.
The buck converter can consume down to 70μA when operating in standby mode.
The RT9996 is available in a VQFN-32L 5x5 package.
