I am using an LM25088 to convert from +19V to -12V.
I would like to be able to control the enable of the LM25088.
But, since the part is reference to -12V instead of GND, I don't think that a 3.3V signal can drive the enable signal directly.
How can I interface a 3.3V signal to enable the LM25088 when used to generate a negative voltage?
The circuit is shown below.
