Abstract
A voltage converter comprising: a bootstrap circuit, comprising an output capacitor, an error amplifier, a charging control circuit and a charging circuit. The charging control circuit comprises: a detection circuit, configured to detect an output voltage of the output capacitor to generate a detection signal; and a power limiting circuit, configured to clamp an output voltage of the error amplifier to a specific range based on the detection signal. The charging circuit is configured to generate a charging signal according the output voltage of the error amplifier to the bootstrap circuit, to charge the output capacitor.
