Intersil Triple/Quad Output Power Management IC Power Management for ISL91211 for Triple/Quad Output Power Management IC

The ISL91211A is a 4-phase, three output programmable Power Management IC (PMIC) and the ISL91211B is a 4-phase, four output programmable PMIC. They are optimized with highly efficient, synchronous buck converters capable of multiphase and single-phase operations that can deliver up to 5A per phase continuous output current. It features four buck controllers and has the capability to reconfigure its power stages to these controllers. This flexibility allows seamless design-in, in a wide range of applications where high output power and small solution size are needed.
