LM25141: Output OVP and UVP function

user4979989

Part Number: LM25141

Hi team,

May I know does LM25141-Q1 implement output OVP and UVP function?

It seems I can't find them on datasheet, but I found the PG pin UV/OV trip level in datasheet page #7 (EC table).

PG(UV) = 92% (typical)

PG(OVP) = 110% (typical)

Thank you.

Regards,

Allen

    Hi Allen,

    The device does not have an OVP function. As the FB voltage increases, the loop will respond by turning on the low side FET for longer to bring down the output voltage.

    For UV, the device will shut down based on the VIN and VCC reaching the UVLO.

    The power good pin will signify the status of the VOUT, as you mentioned above.

    Please let me know if you have any additional questions.

    Best Regards,
    Katelyn
