DESCRIPTION
The AVS12 kitis an automatic mains selector
(110/220V AC)to be usedin SMPS< 500 W.It composedof2 devices: The Controlleris optimized for low consump-
tion and high security triggeringof the triac.
When connectedto VSS, the mode input acti-
vates an additional option.If the main power
drops from 220Vto 110V, the triac control re-
mains lockedto the 220V mode and avoids
any high voltage spike when the voltage
comes backto 220V.
When connectedto VDD, the mode input de-
sactivates this option. The TRIACis specially designed for this appli-
cation. An optimization between sensitivity and
dynamic parametersof the triac gate highly
reduces the lossesof supply resistor and al-
lows excellent immunity against disturbances.
