TPS65023RSBR

Product Summary

The TPS65023RSBR is an integrated Power Management IC for applications powered by one Li-IonorLi-Polymer cell, and which require multiple power rails. The TPS65023RSBR provides three highly efficient, step-down converters targeted at providing the core voltage, peripheral, I/O and memory rails in a pro-for Processor Core (VDCDC3)cessor based system. All three step-down converters enter a low-power mode at light load for maximum efficiency across the widest possible range of load(VRTC) currents. The applications of the TPS65023RSBR include Digital Media Players, Internet Audio Player, Digital Still Camera, Digital Radio Player, Supply DaVinci DSP Family Solutions.
