Аннотация:The study tested output voltage pulsations and pulsations of voltage on a flying capacitor when MAX 1759 integrated circuit of DC-DC converter is pumped in a voltage boost mode with an output voltage of 3.6V and 5.2V at an input voltage of 3.2V and a load current in the range of 5...100 mA. The analysis of the results obtained shows that the hysteresis comparator is the basis for the charge pump control. The algorithm for operating the charge pump system is described for the first time in detail
