TTL level "H" 2.0 V - 5.25 V

"L" 0.0 V – 1.0 V

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.

3.2 Remote On/Off Controlled mode

The cross regulation defined as follows, the output regulation should be within the specified range.

3.3 Regulation

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

3.4 Rise Time

DC +5V output maintains at least16mS is full 1oad after power off which hold within para 3.1 under

115V/60Hz and 230V/50Hz condition.

3.5 Hold-up Time

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 3A for PC board circuits to operate. Conversely, PC

board should draw no more than 3A maximum form this pin. This power may be used to operate circuits

such as soft power control.
