It integrates four DC-DC converters and ten LDO regulators, providing all the power rails required by the Tegra SoC in a single chip. The device supports I2C and SPI control interfaces for runtime voltage and sequencing configuration. The 8ZWSR variant defines the specific rail voltage and sequence configuration for a particular Tegra processor SKU. The compact NFBGA package minimizes PCB area while delivering the complete power solution for Tegra-based automotive infotainment, navigation, and ADAS systems.","working_principle":"The TPS6590378 integrates four high-efficiency DC-DC converters that provide the core processor rails (typically 0.7-1.4V at high current), along with ten LDO regulators for lower-current analog and I\/O rails. A central state machine controls the power-up and power-down sequencing according to the Tegra processor's requirements, ensuring rails come up in the correct order with appropriate timing. The I2C or SPI interface allows the host processor to dynamically adjust output voltages (for DVFS - Dynamic Voltage and Frequency Scaling), enable\/disable individual rails, and monitor status. The device includes voltage monitoring with interrupt generation for undervoltage and overvoltage conditions. Integrated load switches allow controlled power routing to external subsystems.","pin_description":"
