Note 1: Limits are 100% production tested at T A = +25°C. Limits over the operating temperature range are guaranteed by design.
Note 2: LED current matching is defined as: (I LED - I AVG ) / I AVG
Note 3: Dropout voltage is defined as the LED_-to-GND voltage at which current into LED_ drops 10% from the value at V LED_ = 0.2V.
Typical Operating Characteristics
(Circuit of Figure 2, V IN = 3.6V, EN = IN, driving three white LEDs, T A = +25°C, unless otherwise noted.)
