Overview
The TPS65053RGER 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 efficient power management with two step-down converters and three low-dropout (LDO) voltage regulators.
