POWER GOOD / FAIL SIGNAL (OPTIONAL)
TTL logic high for power good and TTL low for
power fail. When the output voltage reaches 90% of
rated value, a +5V TTL signal will be sent out with a
10~500ms delay; At least 1ms before the output
voltage goes below 90% of the rated value, the TTL
signal will be turned off.
