V OUT AC HOT POWER SUPPLY V AC NEUTRAL RETURN AC GROUND GENERAL NOTES: 1. LOAD THE OUTPUT WITH ITS MINIMUM LOAD CURRENT. 2. CONNECT THE PROBES AS SHOWN. 3. REPEAT THE MEASUREMENTS WITH THE MAXIMUM LOAD ON THE OUTPUT. 10uF .1uF LOAD LOAD MUST BE ISOLATED FROM THE GROUND OF THE POWER SUPPLY SCOPE SCOPE NOTE: USE A TEKTRONIX 7834 OSCILLOSCOPE WITH 7A13 AND DIFFERENTIAL PROBE P6055 OR EQUIVALENT. Figure 42. Differential Noise test setup Note: When performing this test, the probe clips and capacitors should be located close to the load. 13.2.5.11 Timing Requirements These are the timing requirements for the power supply operation. The output voltages rise from 10% to within regulation limits (Tvout_rise) within 2 to 50ms, except for 5VSB - it is allowed to rise from 1 to 25ms. The +3.3V, +5V and +12V1, +12V2, +12V3 output voltages start to rise approximately at the same time. All outputs rise monotonically. Each output voltage reach regulation within 50ms (Tvout_on) of each other during turn on the power supply. Each output voltage fall out of regulation within 400ms (Tvout_off) of each other during turn off. Table 72. shows the timing requirements for the power supply being turned on and off via the AC input, with PSON held low and the PSON signal, with the AC input applied. All timing requirements are met for the cross loading condition in Table 16. Table 71. Output Voltage Timing Item Description MIN MAX UNITS Tvout_rise Output voltage rise time from each main output. 2 50 ms Tvout_on T vout_off Output rise time for the 5Vstby output. 1 25 ms All main outputs must be within regulation of each other within this time.

Time all output voltages stay within regulation after loss of AC. Tested at 75% of maximum load. Delay from loss of AC to de-assertion of PWOK. Tested at 75% of maximum load. 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 (3.3V, 5V, 12V, -12V) 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 5VSB being in regulation to O/Ps being in regulation at AC turn on. Time the 5VSB output voltage stays within regulation after loss of AC.
