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

blanking pulse is available.

voltages for all the above described blocks.

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

spring (clip) being sufficient. Between the heatsink

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.
