RT5091B Overview
The RT5091A/B is a total power management solution for SSDs (Solid State Drive) with dedicated input supply voltages of 3.3V or 5V. The RT5091A/B 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.
