• A common application for charge-pump circuits is in RS-232 level shifters, where they are used to derive positive and negative voltages (often +10 V and −10 V) from a single 5 V or 3 V power supply rail. • Charge pumps can also be used as LCD or white-LED drivers, generating high bias voltages from a single low-voltage supply, such as a battery. Webcondition persists until the input voltage and/or the load current increases. 3 Charge Pump Circuit One recommended method to avoid the conditions discussed in Section 2.2 is to use a simple charge pump circuit to keep the BOOT capacitor continually charged. Figure 4 illustrates this type of charge pump circuit using the NE555 timer. Figure 4.

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. WebSingle-ended charge pump circuits are an elegant approach to system flexi-bility, low-power consumption, minimization of pads and external compo-nents, or area. T he output current of the charge pump can be as high as 4.5mA [23] at lock to provide better spur performance thus less leakage current and small lump in breast that moves
