Part Number: LM5122-Q1
Other Parts Discussed in Thread: LM5022, LM5155, LM5122

Hi Team,

My customer is evaluating LM5122-Q1, their use case Vin is 100V~105V.

They are looking for application circuit to support Vin 100V~105V.

Do we have the related circuit for this requirement? Or do you have any suggestion?

Hi Ray,

What is the output power level of the application? If the power level is low enough it would be possible to use a non-synchronous controller like the LM5155 or the LM5022 to achieve this operation.

Thanks,

Garrett

Hi Garrett,

The power level should be 30W~150W.
If my customer's Vin is around 100~105V, do you have the suggestion circuit to overcome high input voltage for LM5122?
