Texas Instruments TPS65220 Power Management IC (PMIC)

Texas Instruments TPS65220 Power Management IC (PMIC) is designed to supply a wide range of SoCs in portable and stationary automotive applications. The device is characterized across an ambient temperature range of -40°C to +125°C, making the PMIC an excellent choice for various industrial automotive applications. The device includes 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 converters require a small 470nH inductor, 4.7µF input capacitance, and a minimum 10µF output capacitance per rail.

Two LDOs support Texas Instruments TPS65220 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 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.
