Switching power supply voltage to maintain a long time: generally up to 20ms or so. What does that mean?
After the power, the output voltage can be maintained for about 20 milliseconds, that is, 0.02 seconds
After the power, the output voltage can be maintained for about 20 milliseconds, that is, 0.02 seconds
The exact explanation is the maintenance time when the voltage drops to 90% of the rated output voltage at full load after the input is de-energized.
