MMPF0200 F6 - SWBST, VGEN2

Hi,

we use the MMPF0200 (F6 configuration) for the supply of a custom i.MX6 solo board.

On my Board, SWBST and VGEN2 are not starting up. I get 0V at VGEN2, and 3.6V at SWBST (no switching).

I think, this may be correct for the F6 configuration. According to table 8, the sequence for this voltages is "-", so this voltages will never start up.

Is this correct?

Are there any details available for this configuration, aside from table 8 in the datasheet?

This is not a issue, since these voltages are unused on my board. But i need to verify, this is not due to an error in my circuit.

Thanks for any help in advance!

Hello Maximilian,

Thank you very much for writing.

Please note that the "-" in the Table 8 from the datasheet, means that the corresponding regulator will be OFF by default, so if you want to use it, you have to turn it ON.

So 0V at the VGEN2 is expected.

In case of the SWBST, I assume you have the incorrect connection.

Please review the Table 1 from the application note AN4751 in order to know the recommended connection when not used.

Please let me know if this information helps.

Regards,

David
