9. POWER GOOD

Note:

1. The Power Good signal is a non-latching open-collector output that is Low during normal operation and is pulled High when any of the following

conditions occur:

• Over-Temperature

• Over-Current

• Vout is outside of the DC Output Band while Vin is within the Vin Operating Range

• Vin is within the Vin Operating Range but the unit is not operating (to determine if 1 Unit used in a parallel

configuration is not operating)

• Vin is outside of the Vin Operating Range

2. The Power Good signal is referenced to Vout(-).
