Electrical Specifications
over the operating temperature range, -40°C to +85°C.
NOTES:
10. Parameters with TYP limits are not production tested unless otherwise specified.
11. Parameters are 100% tested for internal controller prior to module assembly.
12. V
13. The device requires a delay period following an enable signal and prior to ramping its output. Precise timing mode limits this delay period to
14. Precise ramp timing mode is only valid when using the EN pin to enable the device rather than PMBus enable.
15. 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
16. Factory setting for Power Good delay is set to the same value as the soft-start ramp time.
Typical Performance Curves
17. Nominal capacitance of logic pins is 5pF.
