UCC256404: UCC256404EDIT

Part Number: UCC256404


Hello:

We are going to modify the UCC256404 eval kit to get 48V @100 W from 300v-400v input

We will provide the required ac input for xcd current sink.

See  attached spreadsheet calc: from line 180 down I think values are -*** so surely some inputs are inserted incorrectly or out of range elsewhere.

What would that be?

Appreciate any help in the matter.
