Texas Instruments TPS65219/TPS65219-Q1 Integrated PMICs
Texas Instruments TPS65219/TPS65219-Q1 Integrated Power Management ICs (PMICs) for Arm® Cortex-A53 processors and FPGAs are designed to supply a wide range of SoCs in both portable and stationary applications. The devices are characterized by an ambient temperature range of -40°C to +105°C, making the PMICs suitable for various industrial applications. The devices include three synchronous step-down DC-DC converters and four linear regulators. The DC-DC converters are capable of 1x 3.5A and 2x 2A. The TPS65219/TPS65219-Q1 Integrated Power Management ICs require a small 470nH inductor, 4.7μF input capacitance, and (depending on configuration) a 30μF minimum output capacitance per rail.
Two LDOs support output currents of 400mA at an output voltage range of 0.6V to 3.4V. These LDOs support bypass mode, acting as a load switch, and allow voltage changes during operation. The other two LDOs support output currents of 300mA at an output voltage range of 1.2V to 3.3V. The TPS65219/TPS65219-Q1 devices also support load-switch mode. The I2C interface, I/Os, GPIOs, and multi-function pins (MFP) allow many SoCs to interface seamlessly. The TPS65219-Q1 devices are AEC-Q100 qualified for automotive applications.
