SS215X
Overview
SS215X is a SoC with an integrated 5V synchronous buck-boost module that includes charger management, power path management, high-precision ADCs, and rich interfaces. It is suitable for all kinds of intelligent hardware devices that need to be charged and discharged through a USB port, and effectively reduces the development difficulty, PCB area and BOM cost of the overall solution and brings high integration, high flexibility and streamlined peripheral devices.
