Hi
when using a flashlight with linear driver,,the current at the beginning is constant until the point that the battery voltage is too low and the flashlight getting to direct drive by passing the linear drive.
so when using a different flashlight that is direct drive with pwm.does the pwm working all the time untill the battery is dead or at some point when the battery voltage decrease,the pwm chip will be passed(like the linear drive)and the led will e feed directly from the battery?(whenever it in the high mode or lowers modes)
