hi everyone
first, i'm sorry if my question is noob
i want to drive my infrared LEDs with pulsed high current(mine are SFH485P) using simple 555. i problem is that i can't fully understand it's datasheet information here is it's pulsating curve
and voltage drop table
could anyone tell me what 1 A & tp=100us means? is this means that if i want to power the LED with 1 A , i don't have permission to drive them more than 10e-4 second duration?
and from curve max duty cycle could be 5%? and it means that it will be powered for 10e-4 second and for 0.0019 second will be off.
am i right?
my aim is to drive LEDs with high frequency pulsed current and sync it with camera to use it in my project (s.th like night vision cameras)
thank you in advance
