The cross regulation defined as follows, the output regulation should be within the specified range.
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 powereddown state of all power rails.
The 5 VSB pin should deliver 5V ± 3% at a minimum of 3.0 A for PC board circuits to operate.
Conversely, PC board should draw no more than 3.0A maximum form this pin. This power may be
used to operate circuits such as soft power control.
DC output rise time is less than 20 mS at nominal line and full load.
3.3 Regulation
3.4 Rise Time
The +12V and +5V output levels must be equal to or greater than the +3.3V output at all times during
power-up and normal operation. The time between any output of + 12V and +5V reaching its minimum
in-regulation level and +3.3V reaching its minimum in-regulation level must be ≤ 20mS.
3.5 +5V DC / +3.3V DC Power Sequencing
PG output maintains at least 11mS after power off which hold within 80% loads
under 230V/50Hz condition.
3.6 Hold-up Time
3.7 5VSB
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.

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

4.1 Input Protection
4.2 Output Protection
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.
4.2.1 Under voltage protection
The +5V/+12V/+3.3V DC output are protected against the under voltage
condition . range value can't be exceed 10.3~11.0V at 12V terminal and
4.2~4.6V at 5V, 2.0~2.4V at 3.3V.
4.2.2 Over Voltage Protection
The +12V/ DC output are protected against the over voltage condition .

can trip and shut down the power supply at 95℃ ±10℃
4.2.5 Over-Current Protection
4.2.6 Over-Temperature Protection
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.
+5V is less than or equal to 24~35A.
+3.3V is less than or equal to 24~35A.
+12V is less than or equal to 270~354A.
