Abstract: A control method for a dimming driver circuit is provided. Firstly, a detecting signal is generated according to a result of detecting a parameter of a power converting unit. Then, the dimming current is compared with a preset current threshold value. If the dimming current is higher than the preset current threshold value, a status information of a switch element of the power converting unit is determined according to the detecting signal, and a first setting is defined. If the dimming current is lower than or equal to the preset current threshold value, the status is determined according to the detecting signal, a pulse ratio in a chopping cycle is calculated, and a second setting is defined. According to the first setting or the second setting, an initial control signal is adjusted to a real control signal to control the switch element.
