Abstract:
1. A DC-DC conversion device, comprising: a control signal generator to generate a control signal according to a delay signal; a conversion module coupled to the control signal generator for converting an input voltage into an output voltage according to the control signal; and a comparison module coupled to the control signal generator and the conversion module for comparing an output voltage of the DC-DC conversion device with a reference voltage to generate a comparison result and outputting the delay signal according to the comparison result, an enable signal and a clock signal, wherein the comparison module comprises: a voltage divider coupled to the conversion module and the comparison module to generate a divided voltage by dividing the output voltage, wherein the voltage divider comprises: a first resistor having a first terminal coupled to the conversion module and a second terminal coupled to the comparison module; and a second resistor having a first terminal coupled to the second terminal of the first resistor, and a grounded second terminal, wherein the first resistor and the second resistor divide the output voltage to generate and input the divided voltage to the comparison module
