Abstract: In described examples of methods and control circuitry to control a multi-level power conversion system with a flying capacitor, a power circuit regulates a regulator input voltage signal to provide a supply voltage signal to the control circuitry. A power switching circuit couples the regulator input to a first terminal of the flying capacitor in response to a second terminal of the flying capacitor being coupled to a reference voltage node in a given switching cycle, and couples the regulator input to the second terminal in response to the first terminal being coupled to an input node of the power conversion system in the given switching cycle.

Abstract: In described examples of methods and control circuitry to control a multi-level power conversion system, the control circuitry generates PWM signals having a duty cycle to control an output signal. The duty cycle is adjustable in different switching cycles. Each switching cycle includes a respective first sub-cycle with a first sub-cycle duration and a respective second sub-cycle with a second sub-cycle duration. The control circuitry controls a given switching cycle's first and second sub-cycle durations to control a voltage across a capacitor of the power conversion system while maintaining the given switching cycle's duty cycle.

Abstract: An apparatus includes: a switched capacitor (SC) converter to generate a first voltage based on a voltage source; and a direct current-to-direct current (DC-DC) converter to generate a second voltage based on the voltage source of the apparatus. A difference between the first voltage and the second voltage corresponds to an output voltage.

Abstract: In described examples of methods and control circuitry to control a power conversion system, a regulator circuit is coupled to provide switching control signals according to a regulation signal to operate a plurality of converter switches to generate a voltage signal at a switching node. A compensation sense circuit is coupled to provide a compensation pulse signal having a duty cycle that represents a percentage of time that a current flowing through the switching node is above a threshold value. A current compensation circuit adjusts the regulation signal according to the compensation pulse signal.
