Voltage at CS Pin will vary linearly with load current on main output, and will be
6 V at rated load current, when the output voltage is at its rated value.
Open collector. As soon as AC input voltage and DC output voltage are in the
predefined range, the PWR_GOOD signal is set to HIGH.
Will turn ON as soon as PWR_GOOD signal is set to HIGH
Refer to IPC 9592B and Delta Internal Guideline
