Abstract
A circuit for controlling a switch of a power converter. The circuit includes loop control circuitry configured to generate a control signal based on a feedback signal for the power converter and undervoltage circuitry. The undervoltage circuitry is configured to compare a voltage for a capacitor of the power converter with a voltage threshold. The undervoltage circuitry is further configured to, in response to the voltage for the capacitor of the power converter being greater than the voltage threshold, generate a switching signal to drive a switch of the power converter based on the control signal. The undervoltage circuitry is further configured to, in response to the voltage for the capacitor of the power converter being less than the voltage threshold, generate the switching signal to drive the switch of the power converter to the switched-in state until an inductor current is greater than an electrical current threshold.
