Texas Instruments TPS6522005-EP PMICs

Texas Instruments TPS6522005-EP Power Management Integrated Circuit (PMIC) is designed to supply a wide range of SoCs in portable and stationary applications. This PMIC provides three step-down converters and four linear regulators. The TPS6522005-EP PMIC functions at -55°C to 125°C ambient temperature range, which makes PMIC an excellent choice for various industrial automotive applications. The PMIC converter needs a small 470nH inductor, 4.7µF input capacitance, and a minimum 10µF output capacitance per rail. The LDO1 and LDO2 support output currents of 400mA at a 0.6V to 3.4V output voltage range. The LDO3 and LDO4 support output currents of 300mA at a 1.2V to 3.3V output voltage range.

The TPS6522005-EP PMIC is ideally used for low-power industrial MPUs such as AM62x and AM64x with low ambient temperature support requirements. This IC also features an I²C interface, IOs, GPIOs, and Multi-Function Pins (MFP) that allow a seamless interface to a wide range of SoCs. The TPS6522005-EP PMIC devices have gold bond wires, a temperature range of -55°C to 105°C, and an SnPb lead finish.
