8.4.1 Power

Timing

This section discusses the timing requirements for operation with a single power supply. The
output voltages must rise from 10% to within regulation limits (T

vout_rise

) within 5 ms to 70 ms.

The +3.3 V, +5 V and +12 V output voltages start to rise approximately at the same time. All
outputs must rise monotonically. The +5 V output must be greater than the +3.3 V output during
any point of the voltage rise, however, never by more than 2.25 V. Each output voltage shall
reach regulation within 50 ms (T

vout_on

) of each other and begin to turn off within 400 ms (T

vout_off

)

of each other.
