drive by resetting the PWM latch FF1. A Propagation Delay Compensation circuit is added to support immediate
shutdown without delay of the integrated internal CoolMOS™ in the case of current limiting. The influence of the
AC input voltage on the maximum output power can be suppressed as a result.
To prevent the current limiting function from causing distortions by leading edge spikes, a Leading Edge Blanking
circuit is integrated into the current sense path for the comparator C10 and the PWM OP.
