Abstract
A method includes determining that a current at an inductor in a series transfer capacitor buck converter is decaying to zero during a first cycle. The method also includes, in response to determining that the current at the inductor is decaying to zero, enabling an electrostatic discharge (ESD) structure and turning off a low side transistor. The ESD structure is disposed at a node connecting the low side transistor, a high side transistor and the inductor. The method further includes disabling the ESD structure before the high side transistor is turned on during a next cycle following the first cycle.
