Load Balancing
To improve the efficiency of the AS3648 for LEDs with unmatched forward voltage and reduce the internal power dissi-
pation of the AS3648, set the bit load_balance_on =1. This bit can change the currents through the LEDs by up to +/-
15% (up to 115%/85% of set current between LED_OUT1 to LED_OUT2) to match the forward voltage of the LED bet-
ter as shown in Figure 23 :

Flash Strobe Timings
The flash timing are defined as follows:
1. Flash duration defined by register flash_timeout and flash is started immediately when this mode is selected by
2
set strobe_on = 0, start the flash by setting out_on = 1
2. Flash duration defined by register flash_timeout and flash started with a rising edge on pin STROBE (see Fig-
ure 25) :
set strobe_on = 1 and strobe_type = 0
3. Flash start and timing defined by the pin STROBE; the flash duration is limited by the timeout timer defined by
flash_timeout (see Figure 26 and Figure 34 ):
set strobe_on = 1 and strobe_type = 1
