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.

3.4 Rise Time DC output rise time is less than 20 mS at nominal line and full load.
3.5 Hold-up Time PG output maintains at least 16mS is 100% 1oad 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 2.5A 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
03
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.
Output Capacitive load (uF) +5V 10,000 +12V 10,000
4. Protection
4.1 Input 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 Output Protection
4.2.1 Under voltage protection The +5V/+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 2.0~2.4V at 3.3V.

+3.3V 10,000
-12V 350 +5Vsb 10,000
4.2.2 Over 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 16.0V at 12V, 4.5V at 3.3V.
4.2.3 Over Power Protection The power supply can be used electronic circuit to limit the output current against exceeding 50% of surge output power or protected against excessive power delivery since short circuit of any output or over total power at high line.
4.2.4 Short Circuit Protection Short circuit placed on +5V,+12V,+3.3V,-12V will latch off. +5VSB will auto-recovery.
4.2.5 Over-Current 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.
4.2.6 Over Temperature Protection

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.
