TPS65051RSMR Datasheet PDF - TI

●Description

●The TPS6505x family of devices are integrated power-management ICs for applications powered by one Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS6505x devices provide two highly efficient, 2.25-MHz step-down converters targeted at providing the core voltage and I/O voltage in a processor-based system.
