I look for a solution with LT8315: up to 310Vac with 5V output.
Can I use LT8315 for that purpose? Many reference designs are for 12V and above.
Yes, page 21 of the datasheet shows an example.
Thanks W.G. Input side is 90Vac-305Vac. Page 21 is above that, I guess. But I found another circuit for that. Thanks for your help.
