Hello,

Could you explain what you mean by how you want the controller to latch off?

feedback from Foxlink,

During fault conditions such as OVP,OCP,OTP and short circuit. The requirement is latch but the IC is re-start. What we need is latch and recover after ac restart.

thanks, Ian.

it will not fit our current requirement. What we need is latch and can only be reset via AC re-start.

thanks, Ian.

Not only LLC controller but PFC as well. We prefer latest/digital solution.

Hello,

The two digital power supply controllers that we have is the UCD3138 and the C2000 devices.

To see what is available in regards to your design requirements, you will have to repost in the e2e with these two part numbers in the title, so the appropriate applications engineer can look into this for you.
