... Functional Description 3.1 VCC Pre-Charging and Typical VCC Voltage During Start-up In ICE2QS03G, a high voltage startup cell is integrated. As shown in Figure 2, the start cell consists of a high voltage device and a controller, whereby the high voltage device is controlled by the controller. The startup cell provides a pre-charging of the VCC ...

... Once higher than V , but FBZH always lower than V FBR1 Once higher than V FBR1 In the ICE2QS03G, the number of zero crossing is limited to 7. Therefore, the counter varies between 1 and 7, and any attempt beyond this range is ignored. When V exceeds V voltage, the up/down counter FB FBR1 is initialised order to allow the system to react rapidly to a sudden load increase ...
