UC3843: Enable and disable the UC3843

KENNETH M JACKSON
Prodigy 10 points
Part Number: UC3843

Tool/software:

Hi All,

Is there a configuration that allows me to disable the UC3843 at startup and some time later the mcu will enable it?

Any suggestions would be greatly appreciated.

Thanks,

Kenneth

    Hi,

    You can use one of the below to keep UC3843 not producing pulses:

    - Pull COMP pin low - then to enable, to release COMP pin from low

    - Keep its VCC below UVLO on - to enable, raise VCC above UVLO on

    Regards,
