RT9996
Power Management IC for SSD
General Description
Features
z Supply Input Voltage Range : 2.8V to 5.5V
The RT9996 is a 2-CH PMIC for SSD(Solid-StateDrive).
It integrates synchronous buck converters and one voltage
detector.
z Buck 1 / Buck 2
` Adjustable Output Voltage for VCORE or DRAM
Cache
The RT9996 provides 2 independent enable pins for
sequence control and auto discharge when powered off
on the power line of a NAND Flash.
` Output Current up to 1A
z Voltage Detector
` Programmable Threshold Voltage
` Open-Drain Reset Output
z RoHS Compliant and Halogen Free
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.
Applications
z 1.8/2.5 inch Solid-StateDrives
z PortableDevices
z USB-Based Hand-Held Products
The RT9996 is available in a VQFN-32L 5x5 package.
