I need to add remote on/off control to a regulator using the LM22679 - is this possible?

Many thanks

Hi Steve,

If i understand your question correctly, this may require a dedicated Enable pin for an on / off control. Unfortunately the LM22679 do not have this pin available.

You may consider LM61460, which have a dedicated enable pin.

Thank you and i hope that helps

Thanks for the suggestion, but there is no stock of that part and being able to buy it is even more important than the enable pin!

FYI - I'm going with the LM22677
