RT5086D

Power Management Unit Total Power Solution for SSD

The RT5086D is a total power management solution for SSD (Solid State Drive) and applicable the dedicated powered by 3.3V or 5V input. The RT5086D provides six step-down converters, is designed to be flexible PMIC for supporting different output load applications with regulated power sequence.

The RT5086D 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.
