When conversion is enabled and tON_RISE complete, if the output voltage remains between Section 7.6.36 and Section 7.6.35, 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 7-4 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.
