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
