PRODUCTION DATA.
The adjustable QOD can be used to control the power down sequencing of a system even when the system power supply is removed. When the power is removed, the input capacitor discharges at VIN. Past a certain VIN level, the strength of the RPD is reduced. If there is still remaining charge on the output capacitor, this results in longer fall times. For further information regarding this condition, see the Shutdown Sequencing During Unexpected System Power Loss section.
