Boost converter charge pump
WebMay 18, 2012 · A switched capacitor / charge pump boost converter works by repeatedly charging a flying capacitor to an input voltage source and then stacking it on top of the input voltage source. This is achieved in the ideal schematic above by closing alternate switch pairs SW1/SW4 and SW3/SW2. When SW1/SW4 are closed, C1 is charged to voltage … WebSep 7, 2006 · The doubling charge-pump architecture includes four switches, an external energy storage and transfer capacitor commonly known as the “flying capacitor,” and an external output capacitor …

Web3.2 Charge pump circuits. A charge pump circuit is basically a DC/DC charge converter that raises a lower magnitude of voltage by means of energy storage feature of capacitors. So far, the reported efficiencies of the charge pump circuits achievable during voltage conversions are up to 90–95%. WebJul 16, 2024 · Though several inductor-based converters offer amazingly low quiescent current (<10uA maximum), a regulated charge pump is preferred (or required) for cost-sensitive designs that must be intrinsically safe. Off-the-shelf regulated charge pumps with output-current capabilities ≥10mA have typical minimum quiescent currents of 50 to 100µA.
