¹For input and output current specifications, negative current is defined as coming out of the node or pin (sourcing); positive current is defined as going into the node or pin

(sinking).

²Ensured by design and characterization, not production tested.

³Minimum V_IN= 4.5 V is only required at startup. After startup is completed, IC can continue to operate down to V_IN= 3.9 V.

⁴LED current is trimmed to cancel variations in both Gain and ISET voltage.
