摘要
A minimum leading edge blanking (MLEB) signal generator is provided. The MLEB signal generator includes a buck unit and a signal generation unit. The buck unit receives an error amplification signal, and generates a reference blanking signal. The reference blanking signal has a voltage lower than a voltage of the error amplification signal. The signal generation unit receives the reference blanking signal, and generates the MLEB signal according to the current sensing signal. When the current sensing signal is equal to the reference blanking signal, the MLEB signal changes its voltage level. As such, the width of the MLEB signal is a time width of the high level or low level of the MLEB signal before the voltage level of the MLEB signal changes. The MLEB is provided to an external unit, such that the external unit can be prevented from misoperation, thus improving the electric performance in its entirety.
