TDA1675A
when a flyback pulse has been generated. If the
flyback pulse is absent (short cirucit or open cirucit
of the yoke), the blanking output remains high so
allowing the CRT protection.
Pin 13 is an open collector output where the

MOUNTING INSTRUCTIONS
The power dissipated in the circuit must be
removed by adding an external heatsink. Thanks
to the MULTIWATT ® package attaching the
heatsink is very simple, a screw or a compression

and the package, it is better to insert a layer of
silicon grease, to optimize the thermal contact; no
electrical isolation is needed between the two
surfaces.
