Description

The TPS65023-Q1 device is an integrated power management integrated circuit (IC) for applications powered by one Li-Ion or Li-Polymer cell, which require multiple power rails. The TPS65023-Q1 device provides three highly efficient, step-down converters targeted at providing the core voltage, peripheral, input and output (I/O), and memory rails in a processor-based system. The core converter allows for on-the-fly voltage changes through a 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.
