I can't use GDB pin of UCC28070 .

Other Parts Discussed in Thread: UCC28070

I have been developing 7kW interleave converter by using UCC28070. I have just found the problem about output GDB pin which doesn't have signal output. However, I can use only GDA pin to implement in my project which it can be regulated DC output voltage and the ac current nearly sinusoidal. Could you let me know how to solve this problem about GDB pin?

If you are getting a GDA signal and not GDB then you can start by looking at current sense signals CSA and CSB.
What is the input voltage for your application ?
Do you have a schematic ?
