rise time
When power is supplied to a power circuit or similar, the output voltage reaches the specified value over a certain period of time due to transient phenomena. This refers to the amount of time it takes for the output voltage to rise from 10% to 90% of its rated value. It is also the time obtained by subtracting the delay time from the startup time. It is one of the parameters that shows the transient characteristics when power is turned on. When there are many capacitive components in the circuit, the rise time tends to increase due to the charging time.
