In PFCLLCSREVM034 eval board currently the LLC controller goes to normal mode from burst mode at 36W output power (Measured in lab with eval kit). If i have to go to normal mode at 3W output power then what parameter should i change ? Please advice.

Hello,

The burst mode is set by the LL/SS pin of the LLC controller. The data sheet for the LLC controller gives instructions on how to setup this pin based on loading. There is also an excel spread sheet that you can find in the LLC controllers product page design tools folder.
