Overview
The TPS65023RSBR is a highly 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 features three high-efficiency step-down converters and three low-dropout (LDO) voltage regulators, making it ideal for powering various components in processor-based systems. The PMIC supports dynamic voltage scaling, has an I2C-compatible serial interface, and includes several protective features such as thermal shutdown and low ripple PFM mode.
