Dear support member,

My customer used LM4040.

I have a question.

(Question)
Can the LM4040 be used in series as shown below?

Hi Bob

Fixed output voltage version circuit will work fine .

You have to short FB pin to Anode instead of cathode pin for Variable output voltage version in order to get the desired output in the circuit 2.
