Hi,

we perform a battery charger and would like to know how to disable the hiccup OCP of UCC28950 and only keep cycle-by-cycle current limit ?

Thanks,

You could try setting up the voltage amplifier in a voltage follower configuration and use an external voltage amplifier for feedback limiting it's output voltage below the OCP threshold.
