Overview
The TPS65023RSBTG4 is an integrated power management IC (PMIC) designed by Texas Instruments. This device is tailored for applications powered by a single Li-Ion or Li-Polymer cell and requires multiple power rails. It is particularly suited for processor-based systems, providing core voltage, peripheral, I/O, and memory rails. The TPS65023x series, which includes the TPS65023RSBTG4, features dynamic voltage management, enabling on-the-fly voltage changes through an I2C-compatible serial interface. This functionality allows for significant power savings and efficiency optimization.
