2 TPS65219 Overview

The TPS65219 PMIC contains seven regulators; 3 Buck regulators and 4 Low Drop-out Regulators (LDOs). The Buck converters are capable of supporting up to 3.5 A for Buck1, and 2 A each for the remaining buck regulators. LDO1 and LDO2 (2×400 mA) can be configured as load switch and bypass mode to support dynamic SD card voltages, while LDO3 and LDO4 (2×300 mA) can be configured as load switches. With a VIN range of 2.5 V to 5.5 V, the PMIC can support a common 3.3 V or 5 V system voltage. Table 2-1 shows a summary of the voltage and current capabilities for each of the analog resources. With an I2C interface, three GPIO pins, and three multi-function-pins, the TPS65219 PMIC provides the full power package to supply the AM62x SoC, as well as many other SoCs.
