A DC to DC converter includes a control circuit, a gate driver circuit, and a power stage circuit. The control circuit receives and compares a DC output voltage. When the DC output voltage lower than a first threshold voltage, a PWM signal with a first frequency is outputted, and when the DC output voltage higher than the first threshold voltage, the PWM signal with a second frequency is outputted. The second frequency is higher than the first frequency. The gate driver circuit receives the PWM signal and converts the PWM signal to a first driving signal and a second driving signal. The power stage circuit converts a DC input voltage to the DC output voltage according to the first driving signal and the second driving signal. |
