LM3404: LM3404 - CB with short or open

Part Number: LM3404

Hi all

Would you mind if we ask LM3404?

When CB(Boot cap) is open or short, what will LED driver operate?
Our recognition are follows;

Open : High side FET can't operate
Short : High side FET can't operate

Is it correct?

Kind regards,

Hirotaka Matsumoto
