Hello Lawrence,

Do I understand correct that you connect CTRL to VIN and VGH goes to 24V, you connect CTRL to output from controller and VGH does not go to 24V?

Is the same load connected to VGH in both cases? Can you measure the load current in both cases?

Please explain what is shown in the above scope plots.

Best regards,
Brigitte
