Figure 11 : Average Power Dissipation for 100% Duty Cycle vs. One-shot Pulse width.
To calculate average power dissipation
(P) for less than 100% duty cycle :
P100 = average power for 100% duty cycle
τm
P =
P100 where τm = one-shot pulse width
τT
τT = trigger pulse period
=
e.g. : For tm … 600ms tT = 1000ms,
CX = 0.01µF, V = 5V
