Various embodiments relate to a voltage converter including a control unit configured for operating in a hysteretic control mode. A control unit may be configured to receive a PWM signal, a duty cycle signal, at least one reference voltage, a factor of an output voltage of the voltage converter, and a factor of an input voltage of the voltage converter. The control unit may also be configured to compare the at least one reference voltage to the factor of the output voltage and the factor of the input voltage. Further, the control unit may be configured to generate a first control signal mirroring the PWM signal in response to at least one of: the factor of the input voltage being greater than the at least one reference voltage and the factor of the output voltage being greater than the at least one reference voltage. The control unit may also be configured to generate a second, different control signal including a low logic signal in response to the factor of the input voltage being less than or equal to the at least one reference voltage.
