4.2.1 Under voltage protection

3.2 Remote On/Off Controlled mode

The PSON# signal is required to remotely turn on/off the power supply, PSON# is
an active low signal that turns on the output power rails. When this is not pulled low
by the system, or left open, the outputs (except the +5VSB) turn off. This signal is
pulled to a standby voltage by a pull-up resistor internal to the power supply.

TTL level "H" 2.0 V - 5.25 V
"L" 0.0 V – 1.0 V

3.4 Rise Time

DC output rise time is less than 20 mS at nominal line and full load.

3.5 Hold-up Time

DC +5V output maintains at least 8mS after power off which hold within para 3.1
under 230V/50Hz condition.

3.6 5VSB

5VSB is requierd for the implementation of PS-ON described above. 5VSB is a
standby voltage that may be used to power circuits that require power input during
the powered-down state of all power rails. The 5 VSB pin should deliver 5V ± 5% at
a minimum of 2.5 A for PC board circuits to operate. Conversely, PC board should
draw no more than 2.5A maximum form this pin. This power may be used to operate
circuits such as soft power control.

3.7 PG-OK

PG-OK is a power good signal and should be asserted high by power supply to
indicate that the +5 VDC and +3.3 VDC outputs are above the under-voltage
thresholds of the power supply. When this signal is asserted high, there should be
sufficient mains energy stored by the converter to guarantee continuous power
operation within specification. Conversely, when either the +5VDC or the +3.3VDC
output voltage falls below the under-voltage threshold, or when mains power has
been removed for a time sufficiently long so that power supply operation is no longer
guaranteed, PG-OK should be deasserted to a low state. See Figure 1 for a
representation of the timing characteristics of the PG-OK,PS-ON, and germane
power rail signals.

3.8 3.3V Sense

A default 3.3V sense line should be implemented pin 13 of the connector.

3.9 Capacitive Load

The power supply should be able to power up and operate normally with the following
capacitances simultaneously present on the DC outputs.

minimum load connected, neither damage to power supply nor hazards to users
will occur.

to 253Vac/50Hz .

8.3 Insulation Resistance

The insulation resistance should be not less than 30M ohm after applying of
500VDC for 1 minute.

8.4 Dielectric Voltage Withstand

The power supply shall withstand for 1 minute without breakdown the application
of a 60Hz 1500V AC voltage applied between both input line and chassis
(20mA DC cut-off current). Main transformer shall similarly withstand 3000Vac
applied between both primary and secondary windings for a minimum of one minute.

9. Power Good Signal

A TTL compatible signal for the purpose of initiating an orderly start-up procedure
under normal input operating conditions. During power up, this signal is asserted
( low ) until +5V is under regulation and AC reaches min. line specification range.
After all voltage are going appropriate level, the system may have a turn on delay
of 100mS, but no greater than 500mS. During power off the signal should go to
low level before +5V is out of regulation. The low level is 0 to 0.8V and high level
is 4.75 to 5.25V. The " Power Good "signal can drive up to 6 standard TTL loads.
