3.2 Remote On/Off Controlled mode

3.3 Regulation

ST75F-GS

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

3.4 Rise Time

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

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.
