Power Good indicates the status of the converter. (E3h) MFR_SPECIFIC_19 (PGOOD_CONFIG) provides control of the delays asserting and releasing Power Good. Power Good is always low while conversion is disabled, during (60h) TON_DELAY, (61h) TON_RISE, (65h) TOFF_FALL, and during a fault shut-down or hiccup delay. PGOOD_OFF_DELAY is bypassed during (65h) TOFF_FALL and during a fault shut-down or hiccup. Power Good will still be asserted on an unmasked fault event unless that fault's RESPONSE command is configured to Continue Operating without Interruption.

PGOOD_OFF_DELAY and PGOOD_ON_DELAY are sensed and timed independently from each other. If PGOOD_ON_DELAY is less than PGOOD_OFF_DELAY and an unmasked fault or warning event lasts less than PGOOD_OFF_DELAY - PGOOD_ON_DELAY, Power Good will not be asserted low during the fault or warning events.
