TDA8143 - HORIZONTAL DEFLECTION POWER DRIVER
The TDA8143 is a monolithic integrated circuit designed to drive the horizontal deflection power tran-sistor.
The current source characteristic of this device is adapted to the non-linear current gain behaviour of the power transistor providing a minimum power dissipation.
The TDA8143 is internally
