DETAILED DESCRIPTION
Power-Good and Power-Good Delay
A PC power supply is commonly designed to provide a power-good signal, which is defined by the computer
manufacturers. PGO is a power-good signal and should be asserted high by the PC power supply to indicate that
the 5-VDC and 3.3-VDC outputs are above the undervoltage threshold limit. At this time the converter should be
able to provide enough power to assure continuous operation within the specification. Conversely, when either
the 5-VDC or the 3.3-VDC output voltages fall below the undervoltage threshold, or when main power has been
removed for a sufficiently long time so that power supply operation is no longer assured, PGO should be
deasserted to a low state.
The power-good (PGO), DC enable (PSON), and the 5-V/3.3-V supply rails are shown in Figure 3.
Figure 3. Timing of PSON and PGO
Although there is no requirement to meet specific timing parameters, the following signal timings are
recommended:
2 ms
≤ t2 ≤ 20 ms, 100 ms < t3 < 2000 ms, t4 > 1 ms, t5 ≤ 10 ms
Furthermore, motherboards should be designed to comply with the above recommended timing. If timings other
than these are implemented or required, this information should be clearly specified.
