Other Parts Discussed in Thread: UCC29002

Hello,

My customer want to use UCC29002 for the current share of Minus 48V DC Load.
Please give me TI recomended circuit schematic and BOMs.

If the output is -48V then you can use a design that is based on the block schematic below.

The positive output rail is 0V and the negative rail is -48V

John san,

Thank you for your support.
But VDD absolute max. voltage over !
Please give me another cuicuit.

The block schematic I post was intended to demonstrate how to implement load sharing with a negative output voltage.

For any load voltages greater than the 15V max supply rating of the UCC29002 you will need to buffer the VDD and ADJ pins to a max value of 15V

Unfortunately I am unable to locate any high voltage reference designs with the UCC29002
