PROBLEM TO BE SOLVED: To provide a push-pull type transformer line driver that can reduce power dissipation and enhance the power efficiency. SOLUTION: A pair of buffers are connected to a primary coil of a transformer in a push-pull configuration, and a couple of pre-drivers are connected to the pair of the buffers. Each buffer receives a flyback compensation signal generated from the other of the pre-drivers and the buffer using the flyback compensation signal is in operation to cancel a flyback voltage effect induced in the buffer by a line driver signal applied to the primary coil.
