摘要： A regulator control circuit includes a regulator configured to provide an output voltage by regulation using one of an input voltage and a dropped input voltage, to a load; and a heat dissipation circuit configured to sense a change in the input voltage, and provide the dropped input voltage to the regulator when the input voltage is sensed to be equal to or higher than a preset level.

摘要： The present disclosure discloses a vehicle lamp control apparatus. The vehicle lamp control apparatus includes a timing generator configured to detect first and second setting voltages, which are varied, and measure a time in which each of the first and second setting voltages reaches a reference voltage to generate first and second delay times, and a lamp control circuit configured to control sequential turn-on of LED channels using the first and second delay times.
