Abstract:
An LED driving device includes an LED string including at least first and second LED elements connected in series, first and second channels coupled to output nodes of the first and second LED elements, respectively, first and second regulators to regulate a current flowing through the first and second channels in response to first and second control voltages, respectively, and a control voltage generating circuit to generate the first and second control voltages based on a difference between a reference voltage and a comparative voltage, the comparative voltage being generated based on a sensing voltage, the sensing voltage corresponding to an LED current flowing through the LED string. The control voltage generating circuit includes a reference voltage generator to generate the reference voltage based on an input voltage and the dimming signal, the input voltage being supplied to the LED string, the dimming signal controlling dimming of the LED string.
