General Description

The TPS65021 device is an integrated power management IC for applications powered by one LiIon or Li-Polymer cell, and which requires multiple power rails.

The TPS65021 device 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.
