ELECTRICAL CHARACTERISTICS (continued)
(V
Note 2: Specifications over temperature are guaranteed by design and not production tested.
Note 3: 50% of the soft-start voltage time is due to the soft-start ramp and the other 50% is due to the settling of the output voltage.
Note 4: After the voltage at CP exceeds this overvoltage threshold, the entire circuit switches off and autoretry is started.
Note 5: Guaranteed by design; not production tested.
Note 6: FB power good is indicated by PGOOD. The condition V
