Abstract
The disclosure relates to a switched capacitor converter (SCC) with gate driving circuits for limiting currents provided by switching field effect transistors. Embodiments disclosed include an SCC with gate driver curcuits providing gate voltage signals to power FETs, each gate driver circuit comprising first and second gate driver modules and configured to operate in: a first mode in which the first gate driver module provides a gate voltage signal to a power FET that switches between first and second voltage rails by operation of first and second switches connected between the pair of voltage rails; and a second mode in which, in reponse to enabling of a current limit switching signal, the first gate driver module disables switching of one of the first and second switches and the second gate driver module operates to limit a current provided to the power FET.
