LM5036: LM5036 protect

Part Number: LM5036

Hi Sir

pls help check it,tks！

What is the protection mechanism of the LM5036's overcurrent protection and short circuit protection? Whether the control that comes with the chip can be realized, or need to add a short circuit protection circuit. Is the overcurrent protection of this chip limited power or snoring protection?

    Hi Darren Yang,

    Thank you for your interest in this part.

    The over-current protection for this part comes in the form of cycle by cycle peak current limit.

    In addition once the cycle by cycle peak current limit has been activated for a period the part stops switching for a longer period (hiccup).

    Together this means that the part is protected against an output short circuit or over-load condition.

    I would recommend that you use the Excel calculator tool to assist with design of the current limit circuit.
