Abstract
Representative implementations of devices and techniques may minimize switching losses and voltage ripple in a switched capacitor de-de converter. A digital controller is used to control switching, based on an existing load. In some examples, the digital controller may insert a dead-time phase in a switching period, which may reduce voltage ripple for a low output load current. In other examples, the digital controller may adjust the conductance of a plurality of sub-switches, where the plurality of sub-switches may include one or more sub-switches that have a higher on-resistance than other sub-switches. For example, a sub-switch may have an on-resistance that is a multiple of the on-resistance of other sub-switches.
