The TDA1872A is a monolithic integrated circuit in a 15‑lead MULTIWATT package designed for direct drive of the yoke of 110° colour TV picture tubes. It can also be used in portable CTVs, black‑and‑white TVs, monitors and displays.
The document contains a block diagram, pin‑out diagram, absolute maximum ratings, thermal data, DC and AC electrical characteristics, and several example application circuits that illustrate how to use the internal ramp generator, synchronization, blanking and flyback functions.
