A method involves determining that a power converter is in a no-load or ultra-light load mode of operation. In response to determining that the power converter is in a no-load or ultra-light load mode of operation, a voltage amplitude of a feedback signal of the power converter is allowed to rise towards a voltage amplitude that is greater than or equal to a first threshold voltage level. Upon determining that the voltage amplitude of the feedback signal is greater than or equal to the first threshold voltage level, a first sequence of enabling pulses are issued to a primary side switch of the power converter to reduce a voltage amplitude of the feedback signal. Upon determining that the voltage amplitude of the feedback signal is greater than or equal to a second threshold voltage level, a normal mode of operation of the power converter is entered.
