Abstract
A power supply and method of controlling power supplied to a light source are disclosed. The power supply includes a dimming-control voltage generator configured to generate a dimming-control voltage based on first and second adjustment values; a dimming controller configured to output a dimming control signal for controlling analog dimming and pulse width modulation (PWM) dimming of a light source based on the dimming-control voltage; and a driver configured to control the analog dimming and the PWM dimming of the light source based on the dimming control signal.
