FRSET
The flash mode maximum LED current level is
programmed through the FRSET pin. A resistor
connected from the FRSET pin to AGND2 set the
maximum current in the flash mode. This pin can be
grounded if the default flash mode current of 1A is
desired. For the best current accuracy, 0.1% or smaller
tolerance resistor for setting the maximum flash mode
LED current is recommended. This pin cannot be left
floating and the minimum resistance is limited to 17kΩ.
The maximum flash mode current to maximum Torch
mode current ratio is internally fixed as 4 to1.
