Abstract
A buck converter includes a power switch having a first end to receive an input voltage, and a soft start circuit configured to compensate a soft start voltage during a soft start time period according to a result of comparing a feedback voltage corresponding to an output voltage of the buck converter and an input detection voltage corresponding to the input voltage. The buck converter controls switching of the power switch using the soft start voltage.
