1. A secondary-side power supply controller comprising:
a switching section configured to form a drive signal to drive a power switch that is coupled to an inductor in a secondary-side
of a power supply system; and
a burst-mode detector configured to detect the power supply system operating in a burst-mode and responsively inhibit forming
the drive signal, the burst-mode detector including a timer configured to form a first time interval responsively to receiving
less than a first number of occurrences of a sense signal from the inductor during the first time interval wherein the burst-mode
detector is configured to reset the timer responsively to receiving the first number of occurrences of the sense signal prior
to an end of the first time interval.
