Is this really applicable in a closed system as a Cellular phone? The large amount of Capacitors which the Chargepump will apply to the Common Power supply rail (Li-Ion Battery) will cause large ripple currents as the IC charge up. Power will be taken from other IC connected to this rail which might cause malfunction. How do you protect the surrounding electronics from the ripple currents created during startup?
