input mains. The measured wakeup time at 115 Vac and 230 Vac is around 900
milliseconds, which is a common value for this kind of power supply. Thus, thanks to high
voltage circuitry integrated in the L6566B, the wakeup time is constant overthe input voltage
range.
As visible in
undershoot, dip or abnormal behavior is not present during the initial working phase of the
power supply. The power supply has been checked over the input voltage range with same
positive results as shown in the above figures.

voltages. Just a negligible overshoot is present in full-load conditions, without consequences
