LTM8056 LL&MODE PIN

Hi,

My customers are considering LTM 8056.
I got a question.

Sound like a sawtooth wave of about ± 90 mV appears in the output voltage at low load (about 14 mA), and when the output current exceeds 50 mA, noise is eliminated.

#1 Is there no problem with connecting the MODE pin to GND and using the LL pin open?

#2 What is the reason why noise is generated at low load?

Best Regards,

Yuya
