DESCRIPTION

The AVS08kit is an automatic mains selector (110/220V AC)to be used in SMPS<200W.It is composed of2devices:

?The Controller is optimized for low consumption and high security triggering of the triac.When connected to V SS,the mode input activates an additional option.If the main power drops from 220V to110V,the triac control remains locked to the220V mode and avoids any high voltage spike when the voltage is restored to220V.

When connected to V DD,the mode input desacti-vates this option.

?The TRIAC is specially designed for this applica-tion.An optimization between sensitivity and dy-namic parameters of the triac gate highly reduces the losses of supply resistor and allows excellent immunity against disturbances.
