Abstract
A DC-DC converter includes: a master converter configured to operate to generate a panel power voltage based on an input voltage regardless of a panel current, and a slave converter configured to operate to generate the panel power voltage with the master converter based on the input voltage when the panel current is greater than a reference current. The master converter and the slave converter are connected to a first inductor.
