Abstract: Described examples include DC-DC power conversion systems, apparatus and methods for linearizing a DC-DC circuit conversion gain, including a gain circuit providing an output signal according to a gain value and the difference between a first compensation signal and a threshold signal, and a switching circuit selectively operative when the first compensation signal exceeds the threshold signal to linearize the conversion gain by providing a second compensation signal for pulse width modulation of at least one DC-DC converter switch according to the threshold signal and the gain circuit output signal.

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.
