A power converter includes an input node that receives an input voltage and a control loop that regulates an output voltage of the power converter. The power converter also includes a comparison voltage generation circuit that generates a comparison voltage based on an operating point of the power converter. The power converter also includes a first comparator that compares a control loop voltage in the control loop with the comparison voltage, and generates a control signal. The power converter also includes a mode control circuit that transitions the power converter from the low power operating mode to a first operating mode using the control signal. The output voltage is regulated in both the first operating mode and the low power operating mode.
