Abstract

A dimming circuit for digital control includes two output terminals, a voltage sampling unit, an error amplifier unit, and an impedance transforming unit. The MCU voltage generating unit configured for setting the output voltage of the dimming circuit. The error amplifier unit is configured for comparing the voltage value between the two output terminals with the output voltage set by the MCU voltage generating unit. The impedance transforming is configured for adjusting the resistance value thereof according to the output of the error amplifier unit so as that the output voltage value of the dimming circuit for digital control is equal to the output voltage value set by the MCU voltage generating unit. While using the MCU voltage generating unit under programming of the user, the dimming circuitcan automatically perform the output of the LED lamp required by the user.
