part of an off-line SMPS, sending pulses to the slaved TEA2260/61 which are located on the primary 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 2 commanded by I C bus.
