Abstract: Described systems, methods, and circuitries use an interleaved multi-level converter to convert an input signal received at an input node into an output signal at an output node. In one example, a power conversion system includes a first multi-level switching circuit, a second multi-level switching circuit, and a control circuit. The first multi-level switching circuit and the second multi-level switching circuit are coupled to a switching node, the input node, and a reference node. The control circuit is configured to generate, based on the output signal, switching control signals as pulse width modulated signals having a duty cycle to control the output signal and provide the switching control signals to the first multi-level switching circuit and the second multi-level switching circuit.

Abstract: A regulated charge pump power supply is implemented with a QP regulation loop providing QP clocking to control pumping operation based on sensing output voltage using residual charge on a flying capacitor Cfly. Cfly is used not only in normal charge pumping operation as an active charge shuttle element, but also to determine/measure output voltage VOUT. Voltage sensing using measured residual charge on Cfly is accomplished by introducing a sample phase into the normal charge pumping operation—after the pump phase and before the charge phase. In the sample phase, VOUT is determined (sampled) based on the residual charge on Cfly corresponding to (Vsense=VOUT−VIN). During the sample phase, the Cfly bottom plate is connected to ground, and the Cfly top plate is sampled (such as with a sense capacitor), with the sample phase completed prior to initiating a charge phase (by connecting the Cfly top plate to VIN).

Abstract: A switching regulator includes a first transistor having a control input and the first transistor is coupled to an input voltage terminal. The regulator includes a second transistor having a control input. The second transistor is coupled to the first transistor at a switch terminal and to a ground terminal. The regulator also includes a controller coupled to the control inputs of the first and second transistor. The controller configured is configured to cause both the first and second transistors to be off concurrently during each of multiple switching cycles for an adaptive high impedance state. The length of time of the adaptive high impedance state is inversely related to current output by the switching regulator.
