TL;DR: In this paper, a structure and process for converting DC-DC voltages, which allows both buck and boost conversion utilizing a single switched capacitor array, is provided for converting dc-dc voltages.

TL;DR: In this article, a structure and method for converting unregulated DC voltages to regulated voltage using pulse frequency modulation (PFM) and a switched capacitor array capable of multiple gains, where gain selection is based on the output voltage.

TL;DR: In this article, a capacitor array circuit with at least two capacitors, switching circuitry coupled to the capacitors and to input, output and common nodes and control circuitry is described, and the control circuitry operates to sequentially switch the array through three different states so that a voltage is developed across each of the capacitor which is at a fixed value proportional to a voltage present at the input node.

TL;DR: Time-based control techniques for the design of high switching frequency buck converters are presented and eliminates the need for wide bandwidth error amplifier, pulse-width modulator (PWM) in analog controllers or high resolution analog-to-digital converter (ADC) and digital PWM in digital controllers.

TL;DR: In this paper, a delta-sigma control loop for a buck-boost dc-dc converter with fractional gains is presented, which reduces the tones caused by the traditional pulse-frequency modulation regulation.
