The RT5091D is a total power management solution for SSDs (Solid State Drive) with dedicated input supply voltages of 3.3V or 5V. The RT5091D incorporates three high-efficiency synchronous buck regulators and one LDO that deliver several output voltages from a single power source. This provides flexibility to support applications of different VIDs with a regulated power-on sequence.
The RT5091D can provide configurable output voltages to supply ASIC core, DDR, Flash I/O, and PHY. With a dedicated I2C interface, it supports dynamic voltage scaling (DVS), and PS3.5/PS4 power states for minimized standby power consumption.
