DESCRIPTION
The AVS10 kit is an automatic mains selector
(110/220V AC) to be used in SMPS < 300 W. It
is composed of 2 devices :
• The Controller is optimized for low consump-
tion and high security triggering of the triac.
When connected to VSS, the mode input acti-
vates an additional option. If the main power
drops from 220V to 110V, the triac control re-
mains locked to the 220V mode and avoids
any high voltage spike when the voltage is re-
stored to 220V.
When connected to VDD, the mode input de-
sactivates this option.
• The TRIAC is specially designed for this appli-
cation. An optimization between sensitivity and
dynamic parameters of the triac gate highly
reduces the losses of supply resistor and al-
lows excellent immunity against disturbances.
