LMG3425R050: Output Discharge

Hi Kuramochi,

Thank you for your question. What kind of evaluation circuit are you using? The load on the EVM should consume the charge on the output capacitor when the converter is shut down.

Thanks,

Noah

Hi Noah-san,

Thank you for your reply.

>What kind of evaluation circuit are you using?

I will use the EVM and electric load.

>The load on the EVM should consume the charge on the output capacitor when the converter is shut down.

Does it mean that you(TI) do not prepare the discharge circuit when evaluating?

Hi Tadahiko-san,

Are you using the EVM in buck mode? Or is the configuration being changed for something like a double pulse test?

In regards to your second question, you don't need a discharge circuit for the output. Because of the load, the output voltage will naturally drop really fast when shutting down. Is this what you were asking?

Thanks,

Noah

In buck mode.

What does it mean shutting down?

I think that LMG does not have the shutting down function except for the protection function.
