Intel® Server Board S2600GZ/GL TPS Power Supply Specification Guidelines 11.2.15 Timing Requirements These are the timing requirements for the power supply operation. The output voltages must rise from 10% to within regulation limits (Tvout_rise) within 5 to 70ms. For 12VSB, it is allowed to rise from 1.0 to 25ms. All outputs must rise monotonically. The following table shows the timing requirements for the power supply being turned on and off from the AC input, with PSON held low and the PSON signal, with the AC input applied. Table 53.

Delay from AC being applied to all output voltages being within regulation. Time 12Vl output voltage stay within regulation after loss of AC. Delay from loss of AC to de-assertion of PWOK Delay from PSON# active to output voltages within regulation limits. Delay from PSON# deactivate to PWOK being deasserted. Delay from output voltages within regulation limits to PWOK asserted at turn on. Delay from PWOK de-asserted to output voltages dropping out of regulation limits. Duration of PWOK being in the de-asserted state during an off/on cycle using AC or the PSON signal. Delay from 12VSBbeing in regulation to O/Ps being in regulation at AC turn on. Time the 12VSBoutput voltage stays within regulation after loss of AC.
