Hi,

we want to use LP8552 but we can not be sure of its operating temperature spec. In datasheet there writes -30C to +85C at section 7.3 but -40C to +85C at packaging information section. can you please clarify the exact margin? We need -40C for our products.

Hi Sean,
So are you saying there is a possibility of persistent damage at -40C?

Hi Serkan,
It may cause some parametrs not very stable or can't meet the specs on datasheet. But you can refer to LP8556 or TPS61177A/TPS61187 for choice.
