DESCRIPTION
The STV5180 is designed to work in the 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
TV set applications, it contains also a line deflection
control circuit to insure a high level of safety for the
power deflection stage. These two functions are
commanded by I
2C bus.
