Hi Youcef,

Thank you for your interest in LM5122.

Are you still using the same 250kHz switching frequency?

Thanks,

Yinsong

I might use the same frequency (250 khz) if that possible , but if it better to change it to get my specifications then I will

Hi Youcef,

250kHz should be ok. You will need to change the feedback resistors, UVLO resistors if necessary, and COMP RCs (C25, C26, R25) if necessary.

Please let m know if there is any question.

Thanks,

Yinsong
