Figure 2-1 (left) shows 1.2Vo rail for SoC core voltage during power on and off sequence as shown in Figure 2-1 (right). The Inductor current is sharply changed from a full load condition to a light load condition before 1.2Vo rail is trued off. It is a unique load characteristics caused by SoC chipset.
