LOW VOLTAGE DC-DC CONVERTER (LDC) CONTROL APPARATUS FOR PREVENTING OVERHEAT OF LDC AND METHOD OF OPERATING THE SAME

摘要

Disclosed are an LDC control apparatus for preventing an LDC from being overheated, and a method of operating the same. The LDC control apparatus includes a comparator configured to compare a heat release temperature of an LDC with a predetermined criterion temperature, an adjustor configured to adjust a predetermined criterion current value according to a result of the comparison of temperature, and a controller configured to compare the adjusted criterion current value with an output current value being output from the LDC, and control the LDC by converting a control mode of the LDC according to a result of the comparison of current.
