Maximum continuous total DC output power should not exceed 400W. Maximum continuous combined load on +3.3VDC and +5VDC outputs shall not

exceed 120W. Maximum combined load on +12V outputs shall not exceed 300W. When the 12V output is maximum rating, 5V must reach 3A, the output voltage

can be within the specification. When the 5V output is maximum rating, 12V output rating must reach 9A, the

output voltage can be within the specification.

NOTE: Noise test should be measured with 20 MHz bandwidth frequency oscilloscope. The output terminal shall add a tantalum capacitor of 10uF in parallel with a ceramic capacitor of 0.1uF.

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

3.3.1 ST50F-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.

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.

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

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/+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.

4.2 Output Protection

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.

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.
