Hello,

If the device experiences an OV event which passes the PG overvoltage threshold for a time long than the deglitch filter (both specified in the Specifications Section of the datasheet) then the PG pin will be asserted low until the output comes back into regulation.

Best regards,

Ridge

Hello Ridge,

Thank you for response.

When an overvoltage occurs, the PG terminal is set to Low, I interpreted that the output will not be turned off without permission, but is there one?

Regards,

Kentaro

Hi Kentaro,

During an overvoltage event, the buck converter does not disable the output.

Best regards,
