LED DRIVING DEVICE, LIGHTING DEVICE, AND VEHICLE-MOUNTED DISPLAY DEVICE

In an LED driving device, a DC-DC controller performs control such that the voltage at an LED terminal remains equal to a reference voltage, and a reference voltage generator generates the reference voltage such that it decreases as the set value of the LED current set by an LED current setter decre...
