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 shutdown or hiccup delay. PGOOD_OFF_DELAY is bypassed during (65h) TOFF_FALL and during a fault shutdown or hiccup. Power good is still asserted on an unmasked fault event unless the RESPONSE command of that fault 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 is not asserted low during the fault or warning events.
