Abstract
A system includes a high side transistor switch coupled to a first voltage node and a low side transistor switch coupled to the high side transistor switch at a switch node. The system further includes a unidirectional decoupling capacitor circuit including a capacitive component. The unidirectional decoupling capacitor circuit is coupled between the first voltage node and a common potential. Responsive to a voltage on the first voltage node being more than a threshold greater than an input voltage to the first voltage node, the unidirectional decoupling capacitor circuit is configured to sink current from the first voltage node to the capacitive component. The capacitive component can therefore be charged, with the charge used to subsequently power a load.
