摘要
The present embodiments are directed to an improved switched capacitor (SC) converter topology that does not include an inductor. In particular, the topology includes a ladder SC circuit configured as a cap divider, with a gate driving signal being generated to initiate the charging and discharging of the capacitor. In this specific topology, an unregulated output voltage is produced that is a certain fraction of an input voltage of a power source such as a battery. The present embodiments further include a variable frequency modulation (VFM) scheme based on the current-sensing techniques for the gate driving signal generation of the switched capacitor converter.
