LM5119: Add OVP circuit.

David Kim6

Part Number: LM5119

I am using an interleave circuit using the LM5119.

The output voltage requires OVP.

I'm trying to figure out what to do

I want to add an OVP circuit.

Please let me know if you have a good idea.

Hi David,

You can use an external error amplifier to compare Vout and reference votlage (OVP threshold).

Once Vout is higher than OVP threshold, the error amplifier will pull LM5119 UVLO pin low to turn off the part.

Thanks

Qian
