In one embodiment, a single input terminal of a parameter control circuit is utilized to form two different parameters of the parameter control circuit. In another embodiment, the parameter control circuit can include charging and discharging current mirrors.

Parameter control circuit including charging and discharging current mirrors and method therefor

In one embodiment, a power factor correction circuit is configured to use a stored value of a feedback signal to assist in regulating the value of an output voltage and to bypass the sample and hold circuit if the output voltage increase to an upper limit or decreases to a lower limit.

Power factor correction circuit and method therefor

In one embodiment, a secondary-side controller is configured to detect a burst-mode of operation and responsively block or prevent sending drive pulses to a power transistor that is coupled in the secondary side.
