LM25088: How to interface an LVTTL signal to enable the LM25088 when used to generate a negative voltage?

Part Number: LM25088

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.
