LM2611EVAL: Can't get eval board working.

Rick Barfield
Prodigy 20 points
Part Number: LM2611EVAL

Tool/software:

Bought the LM2611EVAL last week.  Powered up yesterday for the datasheet configuration.  5V in, -5V out.  First with no load.  It could not produce -5V.  Can the eval board circuit handle no load?  Also tried with a load for 250mA (datasheet says it can go up to 300mA).

After I get the eval board working in the base configuration, I will have more questions.

    Hello Rick,

    The EVM should be able to work at no load. If you apply 5V on the input it should give -5V on the output. Can you please check if your source is limiting the input current?

    Best regards,
    Brigitte

    Hello Rick,

    As I did not get an answer from you, I expect you have been able to solve the issue you observed and close this thread. If my assumption is wrong, please answer below or if the thread is already locked, start a new one.
