    Hi Kai,

    The traditional solution uses a basic current limit, which can draw close to 12mA current for 32V input. For eight channels this results in a power loss of 3W. This excessive power dissipation causes the board temperature to rise.

    Can you please contact me at anantkamath@ti.com? I can provide more details of our test setup, and the competition device used.

    Rgds,

    Anant
