Abstract
The present invention relates to a dimmer and an input current regulator provided in a power supply. The input current regulator includes: a bleeding circuit generating a bleeding current from an input current passed through the dimmer; a sensing circuit sensing the input current, and controlling the bleeding circuit according to a sense voltage corresponding to the input current; and a biasing circuit generating a power voltage for operation of the input current regulator during operation of the power supply. The input current includes a bleeding current and a power current supplied to the power supply.
