Dear TI Team,

Would you help this request?

I have a question about implementing the TPS23753A function.

Can the TPS23753A implement the Primary-Side Regulation function?

Thank you.

Hi BJ,

We do not currently have a PSR design in our PoE portfolio; however, take a look at PMP10572 for a similar optoless solution:

Hi Thomas,
The recommended solution is a two-chip(PD Interface + PWM) solution.
It is not competitive in price.
PSR method is used to lower the price than the existing method.
(delete : Photo Coupler + Shunt + R + C ...)
Thank you for your help.
