Description
AI
The TPS65219-Q1 is a Power Management IC (PMIC) designed to supply a wide range of SoCs in automotive applications. The device is characterized across an ambient temperature range of -40°C to +125°C, making the PMIC an excellent choice for automotive applications. The device includes three synchronous stepdown DC-DC converters and four linear regulators.
The DC-DC converters are capable of 1x 3.5A and 2x 2 A. The converters require a small 470nH inductor, 4.7µF input capacitance, and a minimum 10µF output capacitance per rail depending on the switching mode configuration.
Two of the 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. These LDOs also support load-switch mode.
The I2C-interface, IOs, GPIOs and multi-function-pins (MFP) allow a seamless interface to a wide range of SoCs.
