The TPS65023, TPS65023BSN0901059, SN0901059B is an integrated Power Management IC for applications powered by one Li-Ion or Li-Polymer cell, and which require multiple power rails. The TPS65023, TPS65023BSN0901059, SN0901059B provides three highly efficient, step-down converters targeted at providing the core voltage, peripheral, I/O and memory rails in a processor based system. The core converter allows for on-the-fly voltage changes via serial interface, allowing the system to implement dynamic power savings. 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 TPS65023, TPS65023BSN0901059, SN0901059B also integrates two general-purpose 200 mA LDO voltage regulators, which are enabled with an external input pin.
