... VCC Precharging and Typical VCC Voltage During Startup A high-voltage startup cell is integrated into the ICLS8082G. As shown in Figure 2, the start cell is integrated into the depletion CoolMOS®. The startup cell consists of a high-voltage device and a controller, whereby the high- voltage device is controlled by the controller. The startup cell provides precharging of the VCC capacitor until the VCC voltage reaches the VCC turned-on threshold V Once the mains input voltage is applied, a rectified voltage occurs across the capacitor Cbus ...
