A voltage converter includes a high voltage regulator, a buck converter and a dual input linear regulator unit. The high voltage regulator converts a rectified voltage to a first load voltage. The rectified voltage is rectified from an input voltage. The buck converter generates an output voltage having a first level based on the rectified voltage during a stabilizing period and provides a transition detection signal that is enabled when the output voltage transitions to the first level. The stabilizing period is successive to an initializing period. The dual input linear regulator unit receives the first load voltage, the output voltage and a reference voltage, generates a second load voltage based on the first load voltage during the initializing period, and generates the second load voltage based on the output voltage during the stabilizing period.
