... Functional Description 3.1 VCC Pre-Charging and Typical VCC Voltage During Start-up In ICL8001G, 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 ...

... To avoid such a situation, the internal foldback point correction circuit varies the V to the bus voltage. This means the V decreased when the bus voltage increases. To keep a constant maximum input power of the converter, the 8 ICL8001G Functional Description is applied to an internal current CS , the output flip-flop is reset. VR ...
