Product Summary

The TPS65012RGZR is an integrated power and batteryor Li-Polymer Cells management IC for applications powered by oneLi-Ion or Li-Polymer cell, and which require multiple power rails. The TPS65012RGZR provides two highly efficient, step-down converters targeted at providing the core voltage and peripheral, I/O rails in a processor-based system. Both step-down converters enter a low power mode at light load for maximumefficiency across the widest possible range of load currents. The applications of the TPS65012RGZR include All Single Li-Ion Cell Operated Products Requiring Multiple Supplies Including: PDA, Cellular/Smart Phone, Internet Audio Player, Digital Still Camera, Digital Radio Player, Split Supply DSP and μP Solutions.
