Abstract
A boost converter includes an input, an output, a startup circuit, a first switch, a comparator circuit, a switching circuit, a control circuit, a converter circuit, and a switch control circuit. The startup circuit boosts an input voltage up to a first output voltage. The comparator circuit outputs a first signal corresponding to the difference between the output voltage and a first reference voltage. The switching circuit outputs a second voltage based on the first signal. The control circuit outputs a second signal corresponding to the difference between the output voltage and a second reference voltage. The converter circuit boosts the input voltage based on the second signal, and outputs the output voltage. The switch control circuit generates a third signal based on the second signal, and outputs the third signal to the first switch.
