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.
