sreenivasarao,

You may want to consider TPS546C23. It has both PMBus and differential remote sense. The limitation is that it is 18 V max input, not 20 V.

Would that possible work for you?

Hi,

Thanks for your reply.

We need current more than 10A for different voltage 1.8V,1.5V,2.5V and 3.3V with Remote sense and SMBUS\I2C features are mandatory.

cost also very important, the suggest part is 35A. Eventually , we don't required this amount of current.

Regards,

srinivasrao.

Alfonso,

Some further research reveals we do have a 20 A option, TPS554B20. Let me know if that would work.

Sreenivasarao,

The lowest current option is 10 A. However, it is a custom device. We would need to know about your end equipment application and business case. You can contact me directly at j(dash)tucker(at)ti(dot)com
