Additional Details

The TDA1170 typically requires a few external components for operation, including resistors, capacitors, and a vertical deflection coil. The flyback generator produces the high voltage required for the vertical retrace period. The thermal protection circuit protects the IC from overheating. The wide supply voltage range allows the IC to be used in a variety of applications. The output stage drives the vertical deflection coil to scan the electron beam vertically across the screen. The device is typically available in a through-hole package.
