* T1 : Turn on time ( 2 sec. Max.)  

 

* T2 : Rise time ( 

 20mS Max.)

* T3 : Power good turn on delay time ( 100 < T3 < 500 mS )
* T4 : Switch on time (0.5 sec. Max.)
* T5 : Power good turn off delay time ( 1.0 mS Min.) PS-ON/OFF
* T6 : Power hold-on time ( 16 mS Min.)
* Power on-off cycle : 
When the power supply is turned off for a minimum of 2.0 sec. and turn on again, the power good signal will 
be asserted.

The MTBF of the power should be 100,000 hours min.

10. MTBF
