Abstract
A power converter having a current limit protection mechanism is provided. An error amplifier of the power converter multiples a difference between (a divided voltage of) an output voltage of the power converter and a reference voltage by a gain to output an error amplified signal. A comparator of the power converter compares the error amplified signal with a ramp signal to output an on-time signal. A current limiting circuit of the power converter detects data related to a high-side switch and a low-side switch of the power converter. The current limiting circuit of the power converter compares working periods and non-working periods of the on-time signal with blanking times to output a current limiting signal. A control circuit of the power converter, according to the current limiting signal, determines whether to control the high-side switch and the low-side switch according to the detected data.
