TPS65023BRSBR Datasheet PDF - TI

●Description

●The TPS65023x device is an integrated power management IC for applications powered by one Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS65023x 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 through 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.
