Internal Overpower Protection
The power delivered by a flyback power supply is
proportional to the square of the peak current in
discontinuous conduction mode:
Unfortunately, due to the inherent propagation delay of
the logic, the actual peak current is higher at high input
voltage than at low input voltage, leading to a significant
difference in the maximum output power delivered by the
