4.4.15 Output Good Signal
Output Good Signal is an open collector output, referenced to COM potential, indicating the status of
the power supply output. While the power supply operates normally, the Output Good is low (0~0.8V).
When the power supply output is disabled due to activated OVP, OTP or FOLD protection, or by OUT
set to off, or by ac ON/OFF set to off, then the output signal stops conducting. The maximum sink
current is 10mA and the maximum voltage is 40VDC.
Typical applications of Output Good Signal
1. In multiple power supply systems, it is possible to disable all the units when a critical unit fails. Refer

2. Hierarchical structure in multiple supply systems:It is possible to define a hierarchy in multiple supply

systems by enabling any N+1 unit by the Output Good signal of the N unit. In this structure, failure of
the N unit will cause all the following units to be disabled. Refer to Fig 4-16 for typical connections
diagram.
The Output Good Signal is referenced to the COM potential, therefore pay attention NOT to
For models with output voltage rating greater than 40V use
a Zener diode to limit the Output Good voltage below 40V.
The resistor and Zener power rating must be greater than the
maximum actual power dissipation.
