Abstract
A current mode Boost converter is disclosed. The Boost converter operates in a pulse width modulation (PWM) mode or a pulse frequency modulation (PFM) mode. To prevent a load current with various probable magnitudes from varying a decision boundary between the PWM mode and the PFM mode, the Boost converter adaptively adjusts a trigger condition for the PFM mode according to a mean value of an inductor current or AC components of an inductor current of an inductor and a slope compensation current.
