Hello Leona,

I do not have this EVM locally and ordered it so that I can verify the behavior here locally. In the meantime could you send a scope shot of the turn on so I can verify the behavior?

Hi Timothy,

The board had stopped working. Vout currently stays low regardless of state of EN. We have reached out to our local FAE to see if we can get a replacement.

VIN = 5V

EN to SW (normally open) (YELLOW)

VOUT = (BLUE)

Thanks,

Leona
