Power Management Unit Total Power Solution for SSD


Update Alert Share

The RT5086A is a total power management solution for SSD (Solid State Drive) and applicable the dedicated powered by 3.3V or 5V input. The RT5086A provides six step-down converters, is designed to be flexible PMIC for supporting different output load applications with regulated power sequence.

The RT5086A 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.
