so the answer is yes? that the current pulses,regarding to the example,will be 5600mA on the high mode when battery voltage is 3v?
what about the issue of battery's voltage drop on high currents?(even if it is pulsed). the image has been taken for flashlight that uses also 3 alkaline aaa batteries.
so even if we take a strong aaa battery like energizer lithium ultimate(stronger when compare to alkaline),even this battery can,only,handle max. 2A pulsed current(when 2sec on/8 sec off=20%dutycycle).so even if we choose the resistor to give us low current like 500mA when the battery voltage is 2.25v and 100% switched:
ronsimpson:...We program the IC to give (in this case) 25% at 3V, 100% at 2.25V
even then,we can't get 2000mA(500*4) when the battery 3v without exceed the 20% duty cycle of the data sheet,and this is before i am talking about higher currents like the PULSED 5600mA or using alkaline batteries.
so how could it be?the flashlight output is more than +200lm~+1000mA,and the led can handle max. 1.8A pulsed current with 10% dutycycle(regarding the data sheet of xr-e led)
i want to mention that i am not argue,i am just try to understand it,something is not make sense to me.
