Notes:

(1) ΔV

F

is the voltage difference between any two LEDs.

(2) Once tripped, flash output will remain disabled until FLEN pin is cycled or reset via serial interface.

(3) Current matching equals ± [I

BL(MAX)

- I

BL(MIN

] / [I

BL(MAX)

+ I

BL(MIN)

].

(4) Test voltage is V

OUT

= 4.0V — a relatively extreme LED voltage — to force a transition during test. Typically V

OUT

= 3.2V for white LEDs.

(5) Dropout is defined as (V

IN

- V

LDO1

) when V

LDO1

drops 100mV from nominal. Dropout does not apply to LDO2 since it has a maximum output voltage

of 1.8V.
