Abstract
A system for controlling an inductor current of a boost converter includes a start-up controller that is configured to generate a control signal that has a fixed on-time duration and a dynamic off-time duration that decreases with each cycle of the control signal, and a pulse width modulation (PWM) circuit that is configured to generate a PWM signal. During a start-up of the boost converter, the PWM signal transitions from a deactivated state to an activated state when the control signal is activated, and from an activated state to a deactivated state when the inductor current is equal to a reference current. The reference current corresponds to a peak value of the inductor current during the start-up. Thus, during the start-up, the duty cycle of the PWM signal increases with each cycle of the PWM signal. The PWM signal is provided to the boost converter for controlling the inductor current.
