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) are configurable for load switch and bypass mode to support dynamic SD card voltages, while LDO3 and LDO4 (2×300 mA) are configurable 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. TPS65219 is characterized for -40°C to +105°C ambient temperature. With an I2C interface, three GPIO pins, and three multi-function-pins, the TPS65219 PMIC provides the full power package to supply the AM243x, as well as many other SoCs and FPGAs.
