LS7637FO Description
Since the operating currents of some electronic transformers are below the holding current of most triacs, a typical triac- OVC - Overcurrent Sense Input (Pin 6) based (leading-edge) dimmer may not operate properly when The voltage at this input is sampled every half-cycle in a driving an electronic transformer-coupled low-voltage halogen four-cycle period. If the voltage reaches the OVC threshold lamp. The...
