Abstract
A voltage monitoring circuit for monitoring an output voltage of a power supply device. The power supply device includes a voltage conversion part that converts an input voltage to the output voltage according to a difference between a feedback voltage based on the output voltage and a first reference voltage. The voltage monitoring circuit includes: a threshold voltage generation circuit configured to generate a threshold voltage from the first reference voltage; and a comparator configured to compare the threshold voltage with the feedback voltage.
