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.

3.3.1 ST70F-ES
The cross regulation defined as follows, the output regulation should be within
the specified range.
DC output rise time is less than 20 mS at nominal line and full load.

DC +5V output maintains at least 16mS after power off which hold within para 3.1
under 115V/60Hz and 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 2.0 A for PC board circuits to operate. Conversely,
PC board should draw no more than 2.0A 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.
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.
T1 : Turn on time ( 2 sec. Max.)
T2 : Rise time ( 20mS Max.)

4. PROTECTION
The power supply should be able to power up and operate normally with the
following capacitances simultaneously present on the DC outputs.
In primary circuit of the power supply, a protected fuse is inserted. Only internal
fault of the power supply will cause the fuse blown. Any overload or short circuit
at DC output will keep from fuse brown or fire hazard.
The +5V/+12V/+3.3V DC output are protected against the under voltage condition.
range value can't be exceed 3.3~3.7V at 5V terminal and 8.5~9.5V at 12V, 2.0~2.4V
at 3.3V.
4.2 Output Protection
4.2.1 Under voltage protection
The +5V/+12V/+3.3V DC output are protected against the over voltage condition.
Maximum value can't be over 6.5V at 5V terminal and 15.5V at 12V, 4.3V at 3.3V.
4.2.2 Over Voltage Protection
Short circuit placed on +5V,+12V,+3.3V,-12V will latch off. +5VSB will auto-recovery.

Current protection should be designed to limit the current to operate within safe
operating conditions. Over current protection schemes where only the voltage
output that experiences the over current event is shut off may be adequate to
maintain safe operation of the power supply and the system; however, damage
to the motherboard or other system components may occur. The recommended
over current protection scheme is for the power supply to latch into the shutdown
state. The setting of over current protection for each output rail is as following.

DC cut-off current). Main transformer shall similarly withstand 3000Vac applied
between both primary and secondary windings for a minimum of one minute.
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.
