    Hi Woo,

    Overcurrent protection uses a dedicated pin and will latch when triggered. It uses the voltage across the resonant capacitor which is proportional to the load current. The description is found in section 7.3.2 of the datasheet: www.ti.com/.../ucc25600.pdf

    Brian Hello ~
    Thank you for your reply.

    I do not wanna be a latch on overcurrent protection.


    Is OCP a Hiccup Mode? Or Current Limit?

    During the test,

    On-off operation time of over current protection becomes faster and on-off operation is stopped at short time.
    (Current Limit)

    What OCP behavior is correct?

    Is it possible to keep on-off at regular intervals during over-current protection?


    I do not know if Google translates correctly ...
    please answer about my question...
    Thank you.
