Webresistor calculated to give a current not exceeding 10mA at the input. Internal power supply To accommodate the wide supply voltage range experienced by the logic and control functions, these devices have an internal power supply. Some parts of the chip are only active when the input is high, the status output and charge pump for example. Webthe charge-pump-stage is operated as a controlled current source InS. Fig. 2 shows a comparison between voltage- and current-mode control 161. If the current source is placed in the discharge path of the charge pump, then CtLr always gets charged to the maximum possible voltage. In phase A, CFLv is then charged to VIN potential.
