TPS65022 Description
The TPS65022 is an integrated Power Management IC for applications powered by one Li-Ion or LiPolymer cell, and which require multiple power rails. The TPS65022 provides three highly efficient, stepdown converters targeted at providing the core voltage, peripheral, I/O and memory rails in a processor based system. All three step-down converters enter a low-power mode at light load for maximum efficiency across the...
