When conversion is enabled and t_{ON_RISE} complete, if the output voltage remains between (43h) VOUT_UV_WARN_LIMIT and (42h) VOUT_OV_WARN_LIMIT, the PGOOD open-drain output is released and allowed to rise to an externally supplied logic level. Upon any fault condition with a shutdown response, the PGOOD open-drain output is asserted, forcing PGOOD low by default. See Table 8-4 for the possible sources to pull down the PGOOD pin.

The PGOOD signal can be connected to the EN/UVLO pin of another device to provide additional controlled turnon and turnoff sequencing.
