Tool/software:

Hi,

Does TPS62825 have OVP function? I can't find any relative wording in datasheet.

Thanks!

    No, it doesn't have Over voltage protection, whereas TPS628302 data sheet, product information and support | TI.com have it.

    "In devices with latch-off protection, there is also an OVP protection circuit that uses the PG window comparator. An OVP event is detected when the FB voltage is approximately 110% × (0.5V) for a period longer than the deglitch time of 35 µs. In this case, the converter de-asserts the PG signal and performs the overvoltage protection function. The converter latches off both high-side and low-side FET and remains in this state. To recover normal operation after a latched short-circuit event, you must cycle VIN or EN."

    Thank you & regards,
