Can a charge pumps output adapt to its input voltage?
Charge pumps can dynamically change their output according to the battery voltage input. For example, a charge pump can operate at either the 1.5X or 1X mode. When the battery input voltage is low, this charge pump produces an output 1.5X the input. The charge pump operates in the 1X mode when the battery voltage is high and the load does not require a voltage boost, so the charge pump merely passes the input voltage to the load. This reduces the input current and power dissipation when the input voltage is high.
