DESCRIPTION
TheSTV5180is designedto workinthe secondary
part of an off-line SMPS, sending pulses to the
slaved TEA2260/61 which are located on the pri-
mary side of the main transformer. Dedicated for
TVsetapplications,itcontainsalsoaline deflection
controlcircuit to insurea high levelof safetyfor the
power deflection stage. These two functions are
commandedby I
2
C bus.
