... If the TRIAC is turning off before the end of the half-cycle erratically or alternate half AC cycles have different conduction angles then flicker will be observed in the LED light due to variations in the output current. This can be solved by including a bleeder and damper circuit. LNK403-409EG PI-5983-060810 Voltage Current 100 ...
