Product Summary
The TPS650240RHBR is an integrated Power Management IC for applications powered by one Li-Ion or Li-Polymer cell, which requires multiple power rails. The TPS650240RHBR provides three highly efficient, step-down 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 widest possible range of load currents. The applications of the TPS650240RHBR include PDA Cellular/Smart Phone, GPS, Digital Still Camera, Split Supply DSP and μ P Solutions: Samsung, ARM-Based Processors, etc.
