About this component
Generates the Lite's main SoC and system rails and handles power sequencing and the RTC under I2C control from the Tegra. The CPU/GPU core rails come from the separate MAX77812 sub-PMIC. Use the H variant, not the Erista A variant, when replacing it. Part variants: Paired with a MAX77812EWB sub-PMIC for the CPU/GPU rails.
