the output voltage ripple at twice the input mains frequency is
measured. As shown it is less than 0.4 V peak-to-peak, which is ideal for LED or lighting
applications. High frequency noise, including spikes, is significantly reduced as well.

In the following illustrations, the MOSFET drain voltage and current are measured at
different line and maximum loads.
