Applications Information (Cont.)

Current Matching

Current Matching refers to the

ΔI from an LED compared to the

average of the minimum and maximum value of all LEDs that are

programmed for the same current.

1x Mode, 1.5x Mode and 2x Mode

1x Mode, 1.5x Mode and 2x Mode all refer to the charge pump

configuration. These modes multiply the input voltage and ensure

that V

OUT is high enough for current to be regulated in the LEDs.

Mode Transition Voltage

Mode transition voltage refers to the input voltage at the point

when the charge pump changes from a weaker mode (lower

numerically) to a stronger mode (higher numerically). V

TRANS1X is

the transition from 1x to 1.5x mode, and V

TRANS1.5X is the

transition from 1.5x to 2x mode.
