efficient protection circuitry. When in the presence of a fault (e. g. failed optocoupler, overcurrent condition, etc. ) the control permanently disables the output pulses to avoid subsequent damage to the system. The IC only restarts when the user cycles the mains power supply. With the low power internal structure, operating at a fixed 60 or 100 kHz, the controller supplies itself from the high--voltage rail, avoiding the need of an auxiliary winding. This feature naturally eases the designer’s.
