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: Described herein is a technology for implementing a scalable SCIB regulator for high conversion step down application. Particularly, the SCIB is configured to include stacked input switch circuits with parallel-connected output switch circuits. The input switch circuits are stacked with or without DC shift switch circuits in between. Furthermore, the input voltage is stepped down to a biasing voltage by input switch circuits and then is regulated to one or more output voltages having one or more independent and predetermined values by output switch circuits. The input switch circuits, output switch circuits and DC shift switch circuits can be modified for scalable power capability and ease of control and manufacturing.

Abstract: In described examples, a DC-DC converter provides electrical power. In response to an input voltage falling below a high voltage operation threshold, the converter repeatedly performs a first normal (N) phase and a second N phase. The first N phase includes delivering power through an inductor from the input voltage. The second N phase includes coupling an input terminal of the inductor to a ground. In response to the input voltage rising above a normal operation threshold, the converter performs a first high voltage (HV) phase, then a second HV phase, then a third HV phase, then the second HV phase, and then repeats from the first HV phase. The first HV phase includes delivering power through the inductor from the input voltage and charging a flying capacitor. The second HV phase includes coupling the input terminal of the inductor to the ground. The third HV phase includes delivering power through the inductor by discharging the flying capacitor through the inductor.

Abstract: In described examples, a DC-DC converter provides electrical power. The converter includes an inductor and a flying capacitor. In response to an input voltage transitioning from below a normal operation threshold to above the threshold, a first transition phase and a second transition phase are repeatedly performed. The first transition phase comprises coupling an input terminal of the inductor to a ground, and the second transition phase comprises delivering power through the inductor by discharging the flying capacitor through the inductor. After the input voltage is above the normal operation threshold, and a voltage across the flying capacitor has reached a target voltage proportional to the input voltage, a charging phase, a freewheeling phase and a discharging phase are repeatedly performed. The charging phase comprises charging the flying capacitor by coupling the flying capacitor to the input voltage, and delivering current from the input voltage through the inductor. The freewheeling phase comprises coupling the input terminal to the ground. The discharging phase comprises coupling the capacitor to the input terminal to deliver current from the flying capacitor and discharge the flying capacitor through the inductor.
