measured at the termination of the VSEN+ and VSEN- sense points.
12. The device requires a delay period following an enable signal and prior to ramping its output. Precise timing mode limits this delay period to
approx 2ms, where in normal mode it may vary up to 4ms.
13. Precise ramp timing mode is only valid when using EN pin to enable the device rather than PMBus enable.
14. The devices may require up to a 4ms delay following the assertion of the enable signal (normal mode) or following the de-assertion of the enable
signal.
15. Factory default Power-Good delay is set to the same value as the soft-start ramp time.
16. Percentage of Full Scale (FS) with temperature compensation applied.

18. Normal capacitance of logic pins is 5pF.
19. Compliance to datasheet limits is assured by one or more methods: production test, characterization and/or design.
