Abstract
Disclosed is an auxiliary apparatus for controlling a current mode of a DC-DC converter. The auxiliary apparatus includes a current mirror coupled to a source voltage and configured to duplicate and supply a reference current supplied from a constant current source, an amplification unit configured to perform negative feedback on a loop control voltage, generated from a DC-DC converter current mode driving unit, and a reference voltage, generated based on the reference current supplied from the current mirror, and a control voltage clamping unit configured to limit a reduction in the loop control voltage based on a gate control voltage output based on a result of the comparison and amplification of the amplification unit.
