Charge pump capacitor output
WebA lower voltage can be output by stacking the diode charge pump stages. There is loss from the Schottky diode at each stage, so the output voltage at N times is calculated using the following formula. V OUT (N) = V IN × N - VF × 2 (N - 1) - α VF: Schottky diode forward voltage α: Other loss Basic circuit (2) Basic circuit (2) WebJul 1, 2006 · Analysis of a basic charge-pump yields a model that accurately preducts performance under a range of operating conditions, while illustrating a general …
