DESCRIPTION
TO220AB
(Plastic Package)
The AVS20 (AVS200) kit is an automatic mains
selector (120/230V AC) to be used in SMPS with
input power < 300 W. It is composed of 2 devices :
• The Controller is optimizedfor low consumption
and high security triggering of the triac. When
connected to VSS, the mode input activates an
additional option “the latched option”. If the
main power drops from 230V to 120V, the triac
control remains locked to the 230V mode and
avoids any high voltage spike when the voltage
is restored to 230V.
When connected to VDD, the mode input desac-
tivates this option “this is the follower option”.
• The TRIACis speciallydesigned forthis applica-
tion. An optimization between sensitivity and
dynamic parameters of the triac gate highly re-
duces the losses of supply resistor and allows
excellent immunity against line disturbances.
