Product Summary
The TPS65051RSMR is an integrated Power Management IC for applications powered by one Li-Ion or Li-Polymer cell, which require multiple power rails.The TPS65051RSMR provides two highly efficient, 2.25MHz step-down converters targeted at providing the core voltage and I/O voltage in a processor based system. Both step-down converters enter a low power mode at light load for maximum efficiency across the widest possible range of load currents. The applications of the TPS65051RSMR include Cell Phones, Smart-Phones WLAN, PDAs, Pocket PCs, OMAP and Low-Power TMS320 DSP Supply, Samsung S3C24xx application processor Supply and Portable Media Players.
