Hi,
We are using UCC25600 for our project which is based of LLC. The system is designed to deliver an output power of 600W.
We are facing some issue in the load regulation of the system; the voltage is not stable; the output voltage keeps dipping during the load range.
The System rating is as below:
Vin: 320 -690 VAC
Vout1: 15V
Iout1: 20A
Vout2: 15V
Iout2 :15A
So, could you please help on this.
The schematic of the same is attached below.
Looking forward to your reply.
Regards,
Sreeni N K
