Overview
The TPS65053RGET is a configurable integrated power management IC (PMIC) from Texas Instruments, designed for applications powered by a single Li-Ion or Li-Polymer cell that require multiple power rails. This device is part of the TPS6505xx family and is particularly suited for processor-based systems, providing core voltage and I/O voltage. It integrates two highly efficient 2.25-MHz step-down converters and three low-dropout (LDO) voltage regulators, ensuring high efficiency and low noise operation across a wide range of load currents.
