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

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

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

transition from 1.5x to 2x mode.
