APPLICATIONS INFORMATION
Power Supply Current
The Electrical Characteristics table specifies the supply
current while the part is idle (waiting to be triggered).
I
voltage. Once triggered, the instantaneous supply current
increases to I
The average increase in supply current ∆I
pends on the output duty cycle (or negative duty cycle,
if POL = 1), since that represents the percentage of time
that the circuit is active. I
