POWER_GOOD#
Live
0
The voltage on the FLB pin is above the required threshold, indicating
that output power is considered good. This bit is the logical inversion of
the PWRGD pin on the part.
1
The voltage on the FLB pin is below the required threshold, indicating
that output power is considered bad.
