LMZ31710: Does the LMZ31710 have OVP protection?

Part Number: LMZ31710

Does the LMZ31710 have OVP protection?
Not indicated on the Datasheet.

  • The LMZ31710 has output over-voltage protection. Here is the description from the internal converter IC used in LMZ31710:

    Output Overvoltage Protection (OVP)

    The device incorporates an output overvoltage protection (OVP) circuit to minimize output voltage overshoot. For

    example, when the load current is abruptly reduced from a high value to a low value, the output voltage response

    can exceed the OVP trip threshold, especially if the capacitance on the output voltage bus is relatively low value.

    The OVP feature minimizes the overshoot by comparing the VSENSE pin voltage to the OVP threshold. If the

    VSENSE pin voltage is greater than the OVP threshold the high-side MOSFET is turned OFF, and the low-side

    MOSFET is turned ON until the OV is discharged. When the VSENSE voltage drops lower than the OVP

    threshold, the high-side MOSFET is allowed to turn ON at the next clock cycle.

    During an OVP event, the low-side reverse current limit still applies, and the device does not allow current flow

    into the PH pin.

  • Dear J Arrigo:

    Good morning.

    Thank you for your reply, but is there any other technical documentation that explains it? There is no explanation on the LMZ317xxx series datasheet.

    Best regards,
