LM5143-Q1: I have Cboot(HB1,HB2) problem of LM5143-Q1 .

Part Number: LM5143-Q1

Hi Sir,

 We have turn on random shut down issue( 2%-3%), but it's normal after turn on.

 Excuse me, What is the recommended value for Cboot of LM5143-Q1 ? I mean that SW pin to HB pin.

It's 0.33uf currently, what happen if Cboot too big?  Will it lead to not booting?

 

Thank you
