Abstract: A constant-frequency current-mode-controlled boost converter circuit provides slope compensation of an inductor current, reduces reverse inductor current in light output load conditions, and reduces oscillation between a discontinuous current mode and a continuous current mode by enabling or disabling an inductor current threshold. The constant-frequency current-mode-controlled boost converter circuit is efficient and stable in light, medium, and heavy output load conditions.
