RT5045A
Power Management Unit Total Power Solution for SSD
General Description
The RT5045A is a total power management solution for
SSD (Solid State Drive) and applicable the dedicated
powered by 3.3V or 5V input. RT5045A provides six
step-down converters, one LDO and is designed to be
flexible PMIC for supporting different output load
applications with regulated power sequence.
RT5045A provides configurable outputs for core power
of SSD controller, NAND Flash memory, I/O power and
DRAM power. It supports dynamic voltage scaling by a
dedicated I²C interface and also apply low power mode
to minimize the standby power consumption.
