Figure 8-7: Startup Time
Startup time can be calculated as follows.
1. Startup time (typ) = 650[ms]
2. CCOM = 10 µF × (1 ±
α/100)
CCOM is a capacitor connected to Terminal C_L/C_R including capacitance variance.
α = Capacitance variance[%]
3. Startup time = Start up time (typ) ×
(1±α) [ms]
For example, CCOM = 11
µF then α = (11 µF – 10 µF)/10 µF = 10[%]
So, Startup time = 650 ms
×(
1+10/100
)
= 715[ms]
