Abstract
A current-mode buck converter is disclosed, wherein the current-mode buck converter operates in a pulse width modulation (PWM) mode or a pulse frequency modulation (PFM) mode. When the current-mode buck converter enters into the PFM mode, the voltage level of the parking voltage is maintained at the voltage level of compensation voltage, so as to decrease switch loss of the current-mode buck converter operating between PWM mode and PFM mode, and stabilize the output voltage of the current-mode buck converter.
