REF5050: high voltage input

Hello Brian,

Please have a look at REF102 and REF02 offering from TI for the 20V support.

May I know details about customer power supply scheme which demands 20V input support. Also, what is the expected variation on the 20V input.

Thanks & Regards,

Shridhar.

There is a high voltage from 17V flyback connected to REF IC to convert the 5Vref to the comparator circuitry for MD braking application. 

However, customer needs 105degree ambient operating temp at least. thanks. 

Hello Brian,

REF102 and REF02 are the best and only option here. Thanks.

Hello Brian.

Do we know if the 17V output from flyback is used to power any other components in the system?

Can the 17V output be changed to lower voltage e.g. 15V. This will ensure REF50 voltage ratings is not violated.

Please check if other components in the system will work with 15V supply. That is one workaround.

Thanks & Regards,

Shridhar
